The best manta ray night snorkel tours on the Big Island all start the same way: a short boat or canoe ride out from the Kona coast just after dark, lights in the water, and giant rays gliding up to feed on plankton right below you.
The Travel Channel has called this experience one of the top ten things to do in your lifetime, and our guests at Blue Hawaiian Activities tell us it lives up to that billing.
What most visitors do not realize is how different the tours are. Some run big catamarans with ride-along seating, while others paddle out on a double-hull canoe with six guests, total.
This guide compares the options we book most often, so you can match the right vessel, time, and group size to your party before spots fill up.
Key Takeaways

- Options range from 50-foot catamarans to six-person double-hull canoes
- Minimum ages vary by tour, from 5 to 7 years old
- Sunset sail combos add a Kona coast cruise before the manta snorkel
How a Manta Ray Night Snorkel Actually Works
Manta rays feed on plankton, and plankton gather around light. Crews position bright light boards or lit floats in the water, guests hold the perimeter, and the rays loop and barrel-roll through the glow to feed.
You float on the surface the whole time. On the tours we offer, guests remain at the surface holding onto a float or light board.
These are wild animals, not trained ones. Most operators offer a manta guarantee that lets you return another night if the rays do not show, and we cover the details tour by tour below.
At Blue Hawaiian Activities we consider this the signature after-dark activity on Hawai’i Island, and it pairs well with the rest of the best things to do on the Big Island.
The Best Boat-Based Manta Ray Night Snorkels
Boat tours are the most common way to do this, and they suit most travelers. Here are the ones Blue Hawaiian Activities recommends first.
Night Manta Experience
The Night Manta Experience with Sea Quest departs from the mouth of Keauhou Bay, just a five-minute boat ride from one of the most consistent manta viewing spots on the island.
It runs nightly at approximately 6:15pm and 8:00pm depending on season, lasts about 1.5 hours, and includes wetsuits, snorkel gear, in-water guides, and hot chocolate with cookies afterward.
Know before you book: children under 7 are not allowed, you must be able to swim on your own with previous snorkeling experience, and you need to climb a small swim ladder back onto the boat.
Sightings are guaranteed. If the mantas do not appear, you can go again free on another Night Manta Experience or a confirmed afternoon snorkel within one year.
Manta Ray Night Snorkeling Tour on the Hula Kai
The Manta Ray Night Snorkeling Tour runs Monday, Wednesday, and Friday aboard the Hula Kai, with departure times that shift seasonally with sunset.
The ride out to Manta Village, near the Outrigger Keauhou Resort, is short. You get about 45 minutes in the water, then warm homemade soup, dinner rolls, and hot drinks back on board.
Ages 7 and up, all guests must be able to swim, and prior snorkeling experience is highly recommended. Full face snorkel masks are not permitted.
Night Manta Ray Snorkel Tour with Sea Paradise
Sea Paradise has been running manta trips since 1985. Its Night Manta Ray Snorkel Tour sails aboard the Hoku Nui, a 50-foot luxury catamaran, out to the well-known Manta Ray Village.
Snorkel time runs about 45 minutes, with light snacks and non-alcoholic drinks after. If someone in your group prefers to stay dry, ride-along guests can watch the rays from the deck, which is a real advantage of the bigger boat.
Two time slots exist as separate listings: the early tour checks in between 6pm and 7pm, and the Late Night Manta Ray Snorkel Tour checks in between 8pm and 9pm. The Hoku Nui is not wheelchair accessible.
Manta Ray Night Snorkel Keauhou Bay
The Manta Ray Night Snorkel Keauhou Bay is the quick-strike option: a 3-minute boat ride from Keauhou Harbor, about 1 hour 20 minutes door to door, with roughly 30 minutes of snorkel time.
It is a small-group trip built for travelers who want to skip crowded boats and long harbor rides. Mask and snorkel are included; wetsuits and life jackets are a 10 dollar add-on but not required.
Participants should be capable swimmers comfortable in open ocean, at least 5 years old, and able to climb a boat ladder. Check-in times can shift with weather and sunset, so keep your phone handy on tour day.
The Best Canoe Manta Snorkels for Small Groups
If a motorboat full of strangers is not your idea of a Hawaiian night, two canoe-based tours offer something quieter. These are the trips Blue Hawaiian Activities suggests for travelers who want the smallest groups on the water.
Canoe Adventure Manta Ray Snorkel
The Canoe Adventure Manta Ray Snorkel with Eka Canoe Adventures rides a Hawaiian double-hull canoe from Keauhou Bay, about 5 to 10 minutes to the snorkel site.
Guests line the perimeter of a custom light board while the rays feed below. The one-hour tour includes snorkel gear, wetsuit tops, and swim noodles; ages 5 and up are welcome, and everyone must be able to float, swim unassisted, and climb a short ladder back into the canoe.
Parking near the pier is free but limited, so allow an extra 10 minutes. A manta guarantee lets you return another evening if the rays do not appear, though no refunds are given for no-show nights.
Night Manta Ray Kayak and Snorkel
The Night Manta Ray Kayak and Snorkel with Anelakai Adventures caps every tour at six people, so you get the undivided attention of your guide and the mantas.
The double-hull canoe is paddle powered: no motors, no gas, no oil. The rays swim right up to the light between the two hulls, and guests who prefer to stay dry can watch from the canoe without getting in the water.
Tours run Monday through Friday for about an hour, with seasonal start times of 6:30pm, 7pm, 8:30pm, and 9pm. This is our pick at Blue Hawaiian Activities for travelers who want the most local-style version of the experience, and one of the most adrenaline-pumping tours in Hawai’i that never actually feels scary.
The Best Sunset Sail and Manta Combos
Want to make a full evening of it? Two tours combine a Kona coast sunset cruise with the night snorkel, and Blue Hawaiian Activities books both regularly for couples.
Sunset Sail & Manta Snorkel – Kona
The Sunset Sail & Manta Snorkel starts with a sail down the Kona coast at sunset, then up to an hour of snorkel time at Manta Ray Village.
The 2.5-hour trip runs on a certified sailing catamaran with a grand staircase for easy water entry, no ladder climbing required. Hot cocoa, tea, and chocolate chip cookies wait for you afterward as the boat cruises back past the lights of Kona town.
All snorkelers must be able to swim without a flotation device, and ride-along guests get a reduced rate. If you do not see a manta, the operator rebooks you free, subject to availability.
This is the combo we suggest most for date nights, alongside the ideas in the most romantic experiences in Hawai’i.
Kona Sunset Manta Ray Snorkel Experience
The Kona Sunset Manta Ray Snorkel Experience departs from Honokohau Marina aboard the vessel KIBOU, with a sunset tour checking in at 5pm and a moonlight tour checking in at 7:30pm.
Each trip runs about two hours, with snorkel mask and fins included. You hold onto a large float in open water while the rays feed, with the western-shore sunset cruise as the warm-up act.
Which Manta Tour Should You Book?
Here is how we sort it at the Blue Hawaiian Activities concierge desk. First-timers and families with kids 7 and up do well on the bigger boats, especially the Sea Paradise catamaran with its ride-along option.
Confident swimmers who want intimacy should go canoe: Eka’s light board tour or Anelakai’s six-person paddle trip. Couples should look hard at the sunset combos.
Short on evening time? The Keauhou Bay small-group tour gets you there and back in under an hour and a half.
One honest caveat: every one of these tours requires real swimming ability, and several want prior snorkeling experience. If that is a concern, ask us about ride-along options before you book.
Popular slots also go fast in high season. Book early in your trip so a windy night can be rebooked, and see which Hawai’i tours sell out first for more on timing.
Conclusion
The best manta ray night snorkel tours on the Big Island come down to the vessel and the vibe: big catamarans for comfort and ride-alongs, double-hull canoes for small groups, and sunset sails for a full evening on the water.
Whichever you choose, Blue Hawaiian Activities recommends locking in your night early and keeping a backup evening free, since mantas and weather both follow their own schedule.
