The 15 Best Day Trips From Rome to Take in 2024 (Our Favorites)

Creating a list of the best day trips from Rome wasn’t easy. I’ve added many of my own favorite day trips in this list, including the ones  that I underestimated at first (like Pompeii and the Amalfi Coast, which I wish I’d had more time to explore). 

So don’t make the same mistakes I did — make plenty of time to see and experience the cities, regions, and sites that most interest you on the list below.

The 15 Best Day Trips From Rome in 2024

If it ends up being more than a single-day trip, so be it! A trip to Rome is a special occasion and your proximity to so many stunning places makes it almost a necessity to spend a little time outside of Rome.

My advice? Pick 2-3 of the places below and schedule at least a day to enjoy and explore. For bigger cities and sites, like the Amalfi Coast and Florence, consider booking a hotel, inn, or guest room to stay for 2-3 days (if your travel dates allow). 

1. Anzio

• 55 minutes by train
• 1 hour 16 minutes by car
• Port city with beaches & military history

Less than an hour from Rome is Anzio, a colorful port city with deep military roots and abundant history. The beauty and cosmopolitan vibes of this long-standing city can almost distract you from what it’s seen in its somber past — this is where U.S. and Britain fought to liberate Rome from Germany during WWII in 1944. 

But that painfully significant history means there’s something to interest everyone here, from the dark military past to the resort-quality beaches and restaurants.

War trenches and military museums, gorgeous beaches, rows of colorful boutiques and shops, sailboats and fishing boats in the harbor, offshore islands to explore and relax on, and adorable Italian restaurants and cafes. 

Head down to Grotte di Nerone di Anzio, the most stunning beach in the city with sparkling white sand as the Tyrrhenian Sea laps the shore. Umbrellas and loungers line the beach and invite you to spend a full day in their comfort, but resist the urge and spend just an hour or two here. 

If you’re a military history buff, this is a prime time to visit the Anzio BeachHead Museum with battle photos and uniforms, preserved foxholes, and veteran-donated artifacts. 

But if you’re setting your sights on beautiful scenery and more secluded beaches, you can take a day trip from Anzio to Ponza Island. The linked tour includes a 5-hour ride around the island with lunch and multiple stops to swim and snorkel. 

You’ll be back from the museum or Ponza Island in time to enjoy your Anzio farewell dinner at a harbor-front restaurant on your way back to the train station or your car. We suggest Il Pizzo di Broccolo and their incredible antipasto tasting menu with 20 seafood starters!

2. Florence

• 1 hour 40 minutes by train
• 3 hours 20 minutes by car
• Historic art museums & grand architecture

Florence is a must-visit city and one of our favorite day trips from Rome, but it’ll take some time to get here — a little under 2 hours by train. It’s well worth the extra time because this is where you’ll see some of the Italian masterpieces, an incredible historical city center with famous architecture, and try some delectable Florentine cuisine. 

Nestled in the scenic hills of Tuscany with a backdrop of rugged mountains framing the view, Florence is dotted with cathedrals featuring domed tops and bell towers (the Duomo), buildings with terracotta-colored roofs, world-class art museums, and excellent restaurants serving Tuscan cuisine. 

Concentrating your day trip to the medieval, walled Centro Storico (historical city center) with cobblestone streets packs the perfect punch for a day trip. Guided tours are the best way to see the highlights of Florence in short order.

The Duomo Area Guided Tour with Giotto’s Tower Climb Ticket takes around 1.5 hours, while you can see masterpieces like “The Birth of Venus” and “Annunciation” with an Uffizi Gallery Small Group Tour (also 1.5 hours).

With a few hours left to enjoy the city, decide between taking a Pasta and Tiramisu Cooking Class from a local expert or stroll the Centro Storico to grab a frozen treat at one of the gelaterias or a pastry at a rustic bakery, pop into local shops and jewelry stores, and finish up with a delectable panini and Tuscan wine at I’ Girone De’ Ghiotti before heading back to Rome. 

3. Tivoli

• 40 minutes by train
• 55 minutes by car
• Scenic hilltop town with historic villas

Head up into the Sabine Hills just 40 minutes from Rome to Tivoli, a delightfully historic little town sitting on the western slopes of the undulating hills overlooking the Aniene River. Known as the “Versailles of Ancient Rome,” the grand villas and once-magnificent villa ruins make it a stunning spot for a day trip.

The best way to see the villas during a day trip when you’re short on time is with a two-in-one guided tour. We recommend the Villa D’Este and Hadrian’s Villa Tivoli Day Tour to see both, which takes about 7 hours in total and includes transportation from Rome along with lunch. 

Hadrian’s Villa, a Roman Emperor’s villa complex and UNESCO World Heritage Site, sits in crumbling ruins. Built around 120 AD, what remains of the villa spreads across 98 acres you can explore, but the highlights are the Canopus (canal), Maritime Theatre (pool surrounded by columns), the Hospital (lavish guest rooms), and a scale model of the villa at the Visitor’s Center. 

Villa d’Este is even more impressive and far from ruins. With 16th-century opulence and luxury originally designed for a Catholic cardinal, the sprawling Italian gardens, grand architecture, and gravity-fed pools, waterfalls, and fountains spilling over hills make it visually stunning. 

After your guided tour, head into the heart of town to sample one of the many gelaterias or stop by the Piazza Plebiscito farmer’s market for fresh produce. End your day trip with a visit to Osteria La Briciola and try the 3-course seafood tasting menu.

4. Vatican City

• 20 minutes by train
• 20 minutes by car
• Historic HQ of the Roman Catholic church

A city-state completely enveloped by Rome, the Vatican City is a city within a city that holds immense religious and historic significance not just for Romans, but the broader Catholic church. This is one day trip you can’t skip from Rome because it’s so close by! 

It’s where you’ll find the Pope’s home, the famed St. Peter’s Basilica, Michelangelo’s ceiling frescoes at the Sistine Chapel, and the hallowed halls of the Vatican Museums. Come to admire the artwork and architecture, step into sacred spaces, or marvel at the history told within the city-state’s walls. 

Touring the city’s highlights can take 4-6 hours, but you’ll need to set a pace for yourself and know which structures, artworks, and exhibits to prioritize. A guided tour makes it easy to schedule your visit and stick to a timetable. 

We really like the Vatican Museums, Sistine Chapel Tour, and St. Peter’s Basilica Entry guided tour with an art historian and the option to add a visit to Castle Gandolfo if there’s time. To beat the crowds, opt for the Early Morning Vatican Museums and Sistine Chapel guided tour. 

You’re going to see iconic works of art, like the ancient “Laocoön and His Sons” and “Apollo Belvedere” Roman sculptures, along with the intricate Vatican Gardens, those famed painted ceilings in the Sistine Chapel, and the Renaissance elegance of St. Peter’s Basilica before your day trip is done. 

5. Naples

• 2 hours 30 minutes by train
• 3 hours 25 minutes by car
• Architecture & art hub of catacomb and pizza fame

The 3rd-largest city in Italy has a laid-back vibe with grand architecture and world-famous cuisine (it’s the birthplace of pizza) that makes it so enjoyable to visit on a day trip from Rome. 

About 2.5 hours from Rome by train, you’ll come here to take in the Centro Storico di Napoli (historic city center) with its 18th-century walls, beautiful Church of Santa Chiara, and the stunning Castel Nuovo. Making sure you don’t miss out on important history and hidden gems is easy with a Naples Old Town and Veiled Christ Tour. 

Strolling through the city center, you’ll come across sculptures that boggle the mind, lush courtyards and gardens, and serene views of the Bay of Naples peeping through.

While you’re here, you can visit the Duomo cathedral and the Baroque opulence of the 16th-century Chiesa di San Gregorio Armeno. But you can’t miss the chance to taste real Neapolitan wood-fired pizza at local favorite spots like Starita or Sorbillo (long lines at both let you know it’s good).

For something a little more unique and hands-on, book an Authentic Italian Pizza-Making Workshop with Drinks (about 2 hours) or a Naples Underground Entry Ticket and Guided Tour to venture deep under the city streets on the northern end of the city to explore the dimly-lit Catacombs of San Gennaro.

6. Abbey of Montecassino

• 1 hour 40 minutes by train
• 2 hours 30 minutes by car
• Historic mountaintop monastery & museum

If your ideal day trip includes religious history, sacred places, and gorgeous views, head south of Rome (about 1 hour and 40 minutes by train) to the secluded Abbey of Montecassino, perched high in the mountains of Lazio.

Massive bronze doors crafted in Constantinople mark the entryway, Renaissance courtyards, arcades, and walkways connect to the cathedral, and beautiful views over the town of Cassino and the surrounding mountains make it one of the best day trips from Rome. 

When you’re here, you’ll be able to marvel at this operational abbey that’s an active pilgrimage site and holds the remains of Saint Benedict, the abbey’s founder, and his twin sister in a bronze urn under the altar. Monks walk the property and if you’re here in time for mass, you’ll hear Gregorian chants. 

This is where the Battle of Monte Cassino — the “Battle for Rome” — was fought in WWII, but this long-standing abbey has rebuilt and risen again from several near-destruction events from its 6th-century roots. 

For the most convenient and educational trip that leads you through the abbey’s storied history and most significant sites, opt for a Montecassino Day Trip from Rome (about 7 hours) that includes your transportation, guided tour, entrance to the abbey and museum, and a visit to the Monte Cassino Polish War Cemetery and the Commonwealth War Cemetery. 

Mostly interested in the wartime history and battles fought at Montecassino? You’ll appreciate hiking the Footprints on the Battlefield Trails of Monte Cassino (about 6.5 hours in total) with a historian guide along hilly Cavendish Road. 

7. Pompeii

• 3 hours 15 minutes by train (1 change)
• 3 hours 30 minutes by car
• Ancient city of ruins from volcanic devastation

The ancient city of Pompeii sits near Naples in the looming presence of Mount Vesuvius, the same volcano that wiped out the city in 79 AD after an unprecedented eruption. Famous for its “frozen” people and crumbling ruins that tell of a once-flourishing city reduced to rubble and ash, Pompeii is one day trip I always recommend from Rome.

It’s one place I believe is worth more than just a day trip. On my trip to Pompeii, I was only able to spend a few hours exploring and wanted more time among the ruins. I wish I would’ve booked an Archaeologist-Guided Tour or a Small Group Tour with an Archaeologist to squeeze more sights in, but you can learn from my mistakes! 

You’ll see plaster casts along the ground of many of the bodies held forever in their final moments. It’s a somber thing — people frozen in time after eruption, huddled in homes or desperately fleeing the city when a cloud of poison gas enveloped the city and instantly killed those who remained.

After being blanketed in thick, volcanic ash, their bones were preserved, later cast in plaster by archaeologists, where they continue to tell the tale of that fateful day. Here in the remains of the city, you can freely explore houses, streets, and structures that were the center of daily life for the people of Pompeii.

The Forum and Forum Baths, the bodies in the Garden of the Fugitives (Orto dei Fuggiaschi), and a massive amphitheater with seating for 20,000 are here. The open-air Teatro Grande and the smaller, covered Odeon theater, where you can hear your voice echo loudly when you stand centerstage, are must-visits. 

Getting to Pompeii presents the small challenge of no direct train lines from Rome leading here, but you can take a high-speed train from Rome to Naples (about 2.5 hours), then take the Circumvesuviana Railway to Pompeii, where you’ll just cross the street to get to the ruins. 

8. Cinque Terre

• 4-5 hours by train (1-2 changes)
• 5 hours by car (to Riomaggiore)
• Colorful cluster of cliffside fishing villages

Cinque Terre is a good distance from Rome and features 5 delightfully unique fishing villages, so it’s another day trip that’s best if you can stay overnight and enjoy at least 2 days in its sun-drenched, historic oasis on the northern Italian Riviera. 

Cinque Terre (meaning “five lands”) is so quaint and picturesque that it’s often visited just to see if the reality of these historic villages is as beautiful as the photos. Spoiler alert: It’s even better than the pictures. 

In photos, you can’t smell the fresh pesto and herbed Focaccia Genovese with salt lingering in the air; you can’t feel the sun on your shoulders as you walk through olive groves and vineyards; you can’t feel the smooth-bumpy texture of the old cobblestone streets beneath your feet. 

But on your trip to Cinque Terre and its 5 villages (Riomaggiore, Manarola, Corniglia, Vernazza and Monterosso), you’ll experience this place with all 5 senses. 

Check out the Hybrid Cinque Terre Boat Tour from Monterosso with a swimming stop to see the gorgeous coastline, take a Private Cinque Terre Trekking Tour, or taste what’s delicious around the villages with a Cinque Terre Food Tour with a local.

Trains connect all 5 towns for fast and convenient travel between them if you’re only here for a day, but there’s also a walking path you can follow to immerse yourself in the area and take in amazing coastal views. 

With a little more time, try the Vernazza Vineyard Trekking Tour with Wine Tasting (3 hours) or take an Authentic Pesto-Making Class in Manarola (1.5 hours). It’s much easier to visit Cinque Terre from Florence (2-3 hours by train) or Pisa (1.5 hours by train) if you’ll be taking day trips to either of these cities from Rome.

9. Castelli Romani

• 40 minutes by train
• 1 hour 20 minutes by car
• Scenic wine region with castles & ruins

Castelli Romani (meaning Roman Castles) is a bucolic oasis in the wine-producing hills just southeast of Rome. Around 40 minutes from Rome via train, this beautifully serene area encompasses 15 villages and towns resting on top of a volcanic crater in the Alban Hills. 

A historic summertime playground for the rich and powerful in Italy, including popes and noble families, the area spans 9,500 hectares of beautiful scenery with lakes and vineyard rows studding the sun-drenched hills. 

The wonders here never seem to cease — medieval castles, ancient ruins, grand villas, and quaint little villages dot the hillsides. It’s one of the most scenic day trips from Rome. It’s so close that you can squeeze it in one afternoon as long as you’re selective about what you’re here to see. 

The best way to experience it all is with a Castelli Romani Hop-On Hop-Off Tour that includes a €20 voucher for food and wine. Ride through the rolling hills past family-owned vineyards, tranquil lakes, imposing castles, and charming medieval villages like Lanuvio, Marino, and Castel Gandolfo (where the Pope spends his summers).

Just here for the vino? Book a Private Castelli Romani Wine Tasting Tour from Rome to make your way through the hilly Frascati wine region of Castelli Romani, enjoying stops at vineyards, tasting rooms, and refreshments paired with sumptuous local wines. 

10. Amalfi Coast

• 2.5–3 hours by train
• 3 hours 50 minutes by car
• Posh coastal oasis of 13 seaside towns

The sparkling Amalfi Coast is nestled a few hours southwest of Rome, offering cosmopolitan towns and seaside villages with some of Italy’s most iconic views and cliffside scenery. Its idyllic 25-mile stretch of cliffside coastline, colorful buildings, and medieval architecture make it a true Italian gem. 

Towns like Amalfi, Positano, Ravello, and Sorrento have made this area famous. Since one day isn’t enough to tour the entire coast town-by-town, you’ll get the most bang for your buck with a tour like the Amalfi Coast and Positano Coastal Cruise from Rome.

After taking a bus from Rome’s Piazza del Popolo to the Salerno harbor, you’ll board a cruise ship and set sail for lovely Positano. There, you’ll be able to explore the narrow Viale Pasitea to wind past restaurants, shops, and villas.

Head down to the beach for a quick swim before cruising to the ancient city of Amalfi. See the medieval Duomo (cathedral), enjoy a limoncello liquor tasting, and walk the picturesque streets along the coast.

Not up for a cruise from Rome? Make your way here, then rent a Vespa to tour the towns of Praiano, Ravello, Amalfi, and Positano like a local, enjoying the sights and ocean breeze along the way. It’s a great way to immerse yourself in the region while zipping through some of the most charming towns on the coast. 

In tiny, mountainous Pianillo, you can attend a Fresh Pasta, Mozzarella, and Tiramisu Class and sip regional wine. Or opt for an Amalfi Coast Sunset Small-Group Boat Tour to watch the sun sink below the horizon and experience the glorious golden hour on the water.

The Amalfi Coast is quite a journey from Rome (nearly 3 hours by train), but it’s conveniently located near Naples (roughly an hour away) if you want to extend your day trip from there. 

11. Assisi and Orvieto

• 1 hour 20 minutes–2 hours by train
• 1 hour 40 minutes–2 hours 20 minutes by car
• Scenic, historic cities known for wine and medieval churches

A drive along the Tiber Valley brings you to the Etruscan town of Orvieto, where you’ll enter the Gothic 14th-century Orvieto Cathedral before continuing through the Tuscan hills, vineyards, and olive groves to reach Lake Trasimeno and Assisi in the shadow of Mount Subasio. 

Assisi, the birthplace of Italy’s patron saint, Saint Francis, boasts amazing architecture and sacred sites like St. Francis’ Basilica and its frescoes, medieval city walls, the People’s Palace, and a former Roman temple to Minerva transformed into a church.

With miles between these equally-stunning and historic cities, you’ll find it easier to opt for a combined day tour like the Assisi & Orvieto Day Trip from Rome that includes transportation, lunch, and entry to the basilicas and cathedrals that make these cities famous.

Prefer breaking things up to explore one or both cities individually? The Assisi Old Town Guided Walking Tour packs lots of history in with entry to the Basilica of Saint Francis, the medieval Church of Santa Maria sopra Minerva, and Roman ruins in the city center. 

The Orvieto Old Town Guided Walking Tour will ensure you see the major sights without spending too much time at any one place, while the 2-hour Cathedral and Pozzo della Cava Underground Tour gives you a closer look at the church and ancient rooms beneath it. 

12. Ostia Antica

• 30 minutes by train
• 47 minutes by car
• Ancient Roman seaport city ruins

Once Rome’s main seaport and a city of extravagance, Ostia Antica sits on the River Tiber and is now an archaeological site on par with Pompeii and Herculaneum. It features preserved ruins that were buried for over 1,000 years after the fall of the Roman Empire.

Ostia Antica makes a fantastic day trip from Rome if you’re into exploring ancient ruins and want to escape the busy city of Rome for a day. The main street running through the city, Decumanus Maximus, is lined with grand arcades (rows of arches) where homes and shops were located. 

You’ll see the ruins of graveyards, temples, churches, public baths, and taverns that depict the fullness of life its citizens enjoyed. Teatro di Ostia, the ancient theater, has been reconstructed and hosts concerts and performances during the summer today. 

The footprint of the city spans about 150 hectares, making it the largest archaeological site in the world. With so much area, it’s wise to book a guided tour to explore and ensure you see the main attractions and best ruins in the city. 

We like the Ostia Antica Half-Day Tour from Rome to pack in the best sights in a 4-hour trip that includes a guide to detail the history of places like the mosaic-studded Baths of Neptune and a medieval well, the Teatro di Ostia, the Square of the Guilds, and the Forum that served as the hub of the city. 

Prefer making your way to the city on your own before starting the tour? A 3-hour Ostia Antica Guided Tour with an Archaeologist begins at the ticket office before continuing through the highlights along the main street and the Forum, or city square. 

Getting here without provided transportation through a guided tour can be a little confusing, but take the train from Rome’s Porta San Paolo Railway Museum toward Columbo. Follow the crowds from the train station at the Ostia Antica stop and walk for about 10 minutes to reach the ruins. 

13. Gardens of Ninfa

• 1 hour 30 minutes by train
• 1 hour 15 minutes by car
• Lavish, picturesque gardens dotted with ruins 

You don’t have to wander far from Rome to see an enchanted land of gardens where stone footbridges cross tiny streams and the River Ninfa. It’s a fairytale brought to life at the Gardens of Ninfa, under 2 hours from Rome. 

Climbing roses, swathes of fragrant wisteria, tropical plants, and ornamental Japanese maples, cherry trees, and ivy transport you into a magical land of natural beauty studded with the remains of a medieval town. 

The Gardens of Ninfa grow on the site of Ninfa, a medieval town since turned to ruins. Now, the 12th-century stone castle walls stand crumbling amid the romantic garden setting with pieces of churches, a reconstructed tower, and restored town hall. 

It’s an absolutely blissful place to escape the buzz and noise of Rome, promising just as much historic value and sightseeing as other famous ruins in Italy, like Pompeii and Ostia Antica. It’s all made even better with the scenic, lush gardens surrounding the ruins. 

The old city of Ninfa was transformed into the gardens of today in the 19th century, designed around English garden principles with 1,300 species of native and exotic plants that make the landscape truly unique. Wandering its serene walking paths will be a highlight of your entire trip to Rome. 

Closed between November and April, this is a spot for warm-weather visit — especially in the late spring, when the trees and flowers are in full bloom. What could be better than a Classic Fiat 500 Rental to make your way to these stunning botanical retreat in style?

If you’d rather rely on public transportation, you’ll need to take the metro from Rome Termini to the Latina Station, then take a taxi, bus, or walk the additional 4 miles to reach the gardens.  

14. Capri

• 2 hours 30 minutes by train to Naples + 40-80 minute ferry to Capri 
• 2 hours 30 minutes by car to Naples + 40-80 minute ferry to Capri 
• Glamorous island with sea caves, upscale dining, and pristine beaches

Synonymous with luxury and located in the sparkling waters of the Tyrrhenian Sea off the coast of Naples, the island of Capri is one that brings pristine beaches, fine dining, and opulent yachts studding the shoreline to mind. 

All this luxury can be yours for a day! Hike scenic paths along the coast or through the inland countryside, set your eyes on rugged cliffs jutting out over the sea, venture into the Blue Grotto sea cave with glowing waters, and enjoy upscale dining, shopping, and sunbathing on iconic white sand beaches. 

For convenience, the popular (and often sold out) Island of Capri Full-Day Tour includes lunch and transportation to the island from Naples over the course of 8 hours. You’ll boat over to the island, visit Marina Grande, Anacapri, and the famous Piazzetta where the notion is to see and be seen. 

Afterwards, stroll the Gardens of Augustus and walk the streets of Camerelle, Tregare, and around the heart of the village. You’ll stop for lunch at a local restaurant (try the ravioli capresi) and see the Faraglioni rock formations before heading back to Naples. 

Looking for something more adventurous? The Capri Island Boat Trip with Grottos lets you explore with a cruise around the island and stops at the Blue Grotto and White and Green Grotto sea caves, Faraglioni sea stacks, and glimpses of the lighthouse, Baths of Tiberius, and villa ruins. 

It takes some dedication to make the island of Capri a day trip from Rome with transportation challenges. If you drive, you’ll need to rent a car and pass toll roads, plus deal with parking. With a train or car ride, you’ll get as far as Naples before you have to board a ferry (slow or high-speed) to reach the island after another 40-80 minutes. 

15. Val d’Orcia

• 2 hours 50 minutes by train
• 2 hours 15 minutes by car
• Scenic Tuscan region of vineyards, groves, and castles

If you want Tuscanesque hills, vineyards, castles, and countryside villages you associate with Italy, head to Val d’Orcia. About 2-3 hours away from Rome, it makes a great day trip if you set out early and have a plan of the sights and villages you want to see. 

This place is quintessential Tuscan countryside. The rolling hills, trees, medieval castles, and historic villages and towns make it feel worlds away from Rome and completely envelop you in Italy’s best scenery.

This part of the wine region is dotted with charming towns like Montalcino and its medieval castle, Bagno Vignoni with its thermal baths, Pienza with Renaissance architecture, the medieval village of Monticchiello, Tuscan cuisine in Montepulciano, and San Quirico d’Orcia with its abundant olive groves. 

Make it special with a Brunello Wine Tasting & Lunch in a Tuscan Castle to enjoy a stroll through the vineyard with a sommelier, taste local wines, and a 3-course Tuscan lunch in the stately Montalcino Castle.

If you’d rather have transportation from Rome included with a private coach, opt for the Tuscany Guided Day Trip with Lunch & Wine Tasting instead. 

You’ll explore culinary and vine delights in Montepulciano after a walking tour, visit a wine cellar and ruins, see the San Biago 16th-century Renaissance church, and enjoy a 3-course lunch with wine in a vineyard farmhouse before strolling around Pienza to shop and explore the streets. 

This is a region that requires a car if you’re not coming as part of a guided tour with transportation. Rent a car and drive up from Rome, or take the train and rent a car once you get to Chiusi so you can make your way between the towns of Val d’Orcia.
