Quick Details — 1st Manta Ray Tour
Quick Details
Sea Paradise has offered manta ray tours since 1985 — one of the original manta tour operators in Hawaii. Manta ray sightings are highly consistent at Manta Village. See the Manta Guarantee. Gratuity not included but greatly appreciated.
What to Expect on the 1st Manta Ray Tour
The Hoku Nui departs Keauhou Bay in the evening for Manta Village — one of the most reliable manta ray viewing sites on Earth. The first departure is the earlier of the evening’s manta tours. The earlier return time makes this the ideal choice for families and guests who prefer to be back ashore early.
Check in
15 min before departure — Keauhou Bay finger pier
Short Cruise
A quick boat ride to Manta Village
Flotation Device
Custom Manta Flotation Device
Snorkel
About 45 min. floating above feeding mantas at Manta Village
Return Sail
Warm drinks & chocolate under the rising stars
At Manta Village, as night falls, our crew deploys underwater lights that attract plankton. The manta rays then feed on the plankton. Guests float on the surface on the custom Manta Flotation Device and watch mantas glide, somersault, and barrel roll just below them in the illuminated water. Sea Paradise captains log every manta sighting after each departure, building one of the most consistent sighting records on the Kona Coast.
Swimming and water safety: For the safety of all guests, the captain and crew may reserve the right to remove a guest from the water, if they determine the guest’s swimming ability or current conditions pose a safety risk. All guests must follow Captain and crew instructions while participating in water activities.

Sea Paradise's 50-Foot Sailing Catamaran
The Hoku Nui — Hawaiian for “Big Star” — is a 50-foot luxury sailing catamaran spaciously designed for 49 guests. That means more deck space, easier water access, and a more relaxed atmosphere from departure to return.
49 Guests
Spaciously designed for 49 guests
50 ft
Twin-hull sailing catamaran
40+ yrs
Operating the Kona Coastline
Our catamaran’s wide twin-hull open design provides a comfortable and stable experience on the ocean, dramatically reducing the rolling motion that causes sea sickness. Guests who are typically sensitive on the water consistently report a comfortable experience aboard the Hoku Nui. The wide beam delivers more usable deck space: shaded seating, two oversized restrooms/changing rooms, a full galley, two freshwater showers, and two wide staircases for easier water entry.
Our USCG licensed captains aboard the Hoku Nui have extensive knowledge of the Kona Coast’s currents, reefs, and conditions and bring years of hands-on Kona ocean knowledge to every departure.










Manta Ray Etiquette
Sea Paradise follows all Manta Ray Tour Operator Guidelines and partners with Manta Ray Advocates Hawaii and the Manta Pacific Research Foundation. The reef manta ray (Mobula alfredi) is listed as vulnerable on the IUCN Red List. Hawaii was the first U.S. state to legally protect manta rays, passing that law in 2009.
Touching
Never touch manta rays — contact removes their protective mucus layer and can cause lasting harm
No Camera Flash
Disable camera flash before entering the water — flash disorients mantas during feeding
Relax
Stay calm and horizontal on the surface — do not dive toward or chase the rays
Go slow in the water
Keep movements slow and deliberate — sudden motion disrupts natural feeding behavior
Passive observation only
Allow mantas to approach naturally — passive observation only
Quiet Voices
Keep voices low and share the moment with aloha
1st Manta Ray Tour FAQ
The 1st Manta Ray Tour (first departure) departs Keauhou Bay in the evening. Exact times shift seasonally throughout the year. Current departure times are listed at seaparadise.com. Check in 15 minutes before your scheduled departure at the end of the Keauhou Bay finger pier — not at any buildings.
Both tours visit Manta Village and follow the same snorkel format. The 1st Tour (first departure) leaves earlier in the evening and has an earlier nighttime return — it is the better choice for families with younger guests and those who prefer to be back ashore earlier in the evening. The 2nd Tour (second departure) departs at dark and offers a quieter, more intimate atmosphere under darker skies with fewer vessels at the viewing site. Both carry the same Manta Guarantee and sighting rates.
Sea Paradise’s manta ray sighting rates run 85–95% — among the highest reliable encounter rates for any wild animal experience in the world. Sea Paradise captains log every sighting after each departure, tracking patterns across nights and seasons.
The Manta Guarantee applies: return free within 7 days if no mantas seen, on a space-available basis.
The Manta Guarantee: return free within 7 days if no mantas seen, on a space-available basis. It is a free rebooking, not a refund. Full terms are available on the Manta Guarantee page.
Yes — as Ride-Along guests. Non-swimmers are warmly welcome to join the manta tour as Ride-Along observers, remaining on deck aboard the Hoku Nui. Ride-Along guests often see manta rays clearly from above the illuminated water and enjoy the full crew briefing, warm drinks and chocolate. All guests must still review our Medical and Health Information and sign a release form (during the booking process) before boarding.
The Kona Coast is home to more than 450 identified reef manta rays (Mobula alfredi), catalogued by Manta Ray Advocates Hawaii and the Manta Pacific Research Foundation using unique belly spot patterns. Famous residents include Lefty — the first Kona manta ever identified, in 1979, recognizable by her damaged left cephalic fin — Big Bertha, one of the largest females with an estimated 14–16 foot wingspan documented since 1991, Koie Ray, known for swimming boldly close to snorkelers, Jolene Ray, a petite regular at about 5 feet wide, and Obama Ray, originally named Barack Obama before being confirmed female. Quarantina, first spotted during the COVID pandemic, and Elvis are among other well-known residents. If you photograph an unidentified manta belly, you can submit it to the Manta Ray Tracker — and if it’s a new individual, you may earn the right to name it.
Warm drinks and chocolates are served after the manta snorkel on the return sail. Non-alcoholic beverages are also available. No alcohol is served on manta tours.
Wear a swimsuit under comfortable clothing. Bring a towel, a light jacket or hoodie for the cooler return sail, and sandals or slip-ons (Sea Paradise operates shoe-less boats). All snorkel equipment including wetsuits is provided. Underwater cameras are welcome — disable any flash before entering the water. Shark Bands Are NOT Allowed as they may repel the manta rays.
Check in at the end of the finger pier at Keauhou Bay — end of Kaleiopapa Street, Kailua-Kona, HI 96740. Do not check in at any buildings. Arrive 15 minutes before your scheduled departure. Free parking is available along Kaleiopapa Street; allow 3–5 minutes to walk to the boat. Public restrooms are on the east side of Kaleiopapa Street near the parking lot. Restrooms/ Changing rooms are also onboard the Hoku Nui.
