What is a Kona night manta ray dive tour?
Swim with wild manta rays under the stars on the Kona coast — one of the only places in the world where this surreal experience happens almost nightly. Tours run year-round, with snorkelers and divers gathering at sunset to witness graceful manta rays feeding in illuminated waters just offshore.
As the sun dips below the horizon in Kona, you paddle out into darkness. Floating under a canopy of stars, you watch light beams dance in the water — and then, like magic, a massive manta ray glides into view. Wings outstretched, it spins gracefully beneath you, feeding on clouds of plankton. It’s a surreal, almost spiritual experience — and one of the most unforgettable things you can do on the Big Island.
Why Kona Is Unique
The Kona coast is one of the only places in the world where you can swim with wild manta rays almost every night. Thanks to underwater lights placed by local tour operators, plankton are drawn in — and with them, the majestic mantas. This phenomenon was discovered by accident in the 1970s and has since evolved into a world-class marine encounter cherished by snorkelers and divers alike.
Unlike seasonal wildlife experiences elsewhere in Hawaii, Kona’s manta ray dives are available year-round, with high success rates and excellent visibility most nights.

Where the Tours Happen

There are two main sites where most manta encounters occur:
- Manta Ray Village (Keauhou Bay): This is the most popular and beginner-friendly location, known for its calm conditions and shallow waters. It’s perfect for first-time snorkelers or families.
- Garden Eel Cove: Slightly farther north, this spot is favored by scuba divers thanks to its deeper reef structure. Conditions can be choppier, but the manta activity is often just as vibrant.
How the Tour Works
Most manta tours begin just before sunset. After checking in, you’ll board a boat for a short 10–20 minute ride to the designated site. Snorkelers float at the surface while holding onto a large light board that attracts plankton. Below, manta rays glide upward in wide, graceful loops — sometimes coming within inches of your mask.
Scuba divers descend to the seafloor, where they kneel and observe the rays from below, silhouetted against the glow. It’s a fully guided experience, and most operators provide wetsuits, snorkel gear, and flotation devices.

Safety & Suitability
Manta rays may look massive, but they’re completely harmless. They have no teeth, no stingers, and pose no threat to humans. Most tours welcome participants ages 10 and up, and all operators prioritize safety, providing full briefings and in-water support.
However, this tour isn’t ideal for non-swimmers or those uncomfortable in open water at night. If you’re unsure, it’s worth speaking with the tour company in advance to determine fit.
Suggested Evening Itinerary

An ideal manta ray night dive experience can be paired with a relaxed Big Island evening:
- 5:00 PM – Enjoy sunset dinner at Magic’s Beach Grill, a casual oceanfront spot in Keauhou
- 6:15 PM – Check in for your tour and gear up
- 7:30 PM – Enter the water for your manta experience
- 9:30 PM – Return to shore, glowing from the experience
What to Bring
Be sure to pack warm layers for after the dive — the ocean breeze can be chilly when you’re wet. A waterproof camera with low-light capability is ideal, as is a towel and dry bag for your personal items. If you’re prone to seasickness, consider taking precautions like Dramamine or ginger beforehand.
Frequently Asked Questions
Not at all. Most guests describe the experience as peaceful and awe-inspiring. Manta rays move slowly and gracefully, and it feels more like flying with angels than swimming with sea creatures.
Do I need to be scuba certified?
Only if you’re doing the scuba portion. Snorkeling tours are open to anyone comfortable swimming in open water.
What if I get cold?
Wetsuits are provided, and the ocean stays around 76–79°F year-round — comfortable, but cool enough to need protection.
What’s the best time of year to go?
While manta sightings are consistent year-round, winter months (November to March) often offer the clearest skies and calmest waters, making for a more magical night overall.
