Big Island Manta Ray Dive Plus 2 More Reef Dives
A Big Island manta ray dive is a bucket list moment, and Puako Dive Adventures gets you closer than almost anyone. Working from the quiet Kohala coast just north of Kona’s crowds, they cap every boat at six divers, so each trip feels like a private charter into Puako’s lava reefs. Their three dives each reveal a different side of the ocean: a sunrise two tank dive when the reef wakes up, a focused manta dive paired with snorkeling for the headline encounter, and an evening two tank dive that follows the reef from golden sunset into its glowing nightlife. If you want the most personal manta experience on the Big Island, this is where we would point you.

Activity Overview
- Scuba diving tours depart from South Kawaihae Small Boat Harbor on the North Kohala Coast, near Spencer Beach Park. Click here for directions.
- If you’re staying in Waimea Town or in the resorts on the Kohala Coast and Waikoloa, this is a convenient spot to go diving.
- Snorkelers are welcome on the dives! Snorkelers float at the surface, where the mantas roll and spin just inches away, often pressing belly-to-belly in unforgettable encounters.
- Divers settle below as mantas sweep silently overhead, sometimes close enough that their bellies brush across your head as they pass.
- All gear is included. If you would like to, you may bring your own gear.
- Choose from three tour types. Details are below
Most divers default to the busy boats out of Kona. We get the appeal, but it means crowded sites and a rushed pace. Puako Dive Adventures takes the opposite approach. They run just north of the crowds along Puako and the Kohala Coast, cap every boat at six divers, and linger where the ocean comes alive instead of racing site to site.
The manta encounter gets you eye-to-eye with the island’s most otherworldly residents, and there are two more dives built around the same small group, slow down and explore philosophy.
Why This Big Island Manta Ray Dive Is Different
A few things set this operator apart from the bigger fleets:
- Only six divers per boat, so every trip feels like a private charter
- Departs from the quiet Kohala coast, away from the packed Kona dive sites
- Volcanic terrain that actually wows: lava arches, caves, ridges, and reefs full of life
- An unhurried pace, so you settle in and watch the reef instead of rushing a checklist
- Welcoming to newer divers as well as seasoned ones, as long as you are certified
- Frequent sightings of manta rays, sea turtles, and reef creatures that look almost alien
The Big Island Manta Ray Dive and Two More Tours
Three dives, three completely different moods. Here is what each one offers.
Close Encounters: The Manta Dive (One Tank Plus Snorkeling)
This is by far their most popular tour. Manta ray scuba diving is a Big Island-only thing to do. This dive is a focused trip built entirely around the manta encounter, the most intimate one on the Big Island, where these giants loop overhead and glide past close enough to feel like you could reach out.
Because it pairs one tank of diving with snorkeling, it is the most flexible option for a mixed group, so a non-diving partner or older kid can snorkel the same water while you dive.
- Runs about 2 hours
- The standout manta experience, belly to belly or overhead
- Tours depart 1 hour before sunset, usually around 5 PM
Sunrise Explorer: The Reef Awakens (Morning Two Tank Dive)
An early start rewards you with calm water and a reef that is just waking up. Over two tanks, you glide through lava landscapes while reef life stirs around you, with great odds of turtles and the clearest light of the day.
- Runs about 4.5 hours
- Two-tank dive at first light
- Calm conditions and lively early morning reef activity
Twilight Protocol: Reef After Dark (Evening Two Tank Dive)
The most dramatic of the three. You drop in during golden sunset and stay as the reef transforms, daytime fish bedding down while the strange and wonderful night creatures emerge. Watching that shift happen around you is the kind of dive you remember for years.
- Runs about 4.5 hours
- Two tank dive from sunset into the dark
- See the reef change over from day life to glowing nightlife
A seasonal bonus: from December through April, they also run humpback whale watching trips, a great non-diving outing if you are traveling with family during whale season.
Why We Recommend Puako Dive Adventures
This is a small, owner-run operation that has been guiding these waters for decades, and it shows in the little things: the tiny group sizes, the patience underwater, and a real respect for the ocean rather than a conveyor belt of tours.
The lead guide is an experienced dive master who has even taken out celebrity divers from the island’s science fiction convention crowd over the years, and the reviews consistently praise how safe and easygoing the trips feel for divers of all skill levels.
For us, that combination is the whole pitch. You get the famous Big Island manta encounter without the crowds, a guide who clearly loves what they do, and a pace that lets the reef reveal itself. If you only have time for one dive operator on this side of the island, this is an easy one to recommend.
A member of our newsletter highly recommended this dive company. They go out annually with them. They say you can’t beat the locations they took you.
Big Island Manta Ray Dive FAQs
Where do the dives leave from?
Boats depart from South Kawaihae Small Boat Harbor on the Kohala coast, then dive the reefs off Puako just to the south. Parking at the harbor is free, and they ask you to arrive about 30 minutes before departure.
Do I need to be a certified diver?
Yes, the dives are for certified divers only, but newer divers are very welcome. The small group size makes it a comfortable setting if you are still building confidence underwater. Snorkelers can join the manta trip without certification.
When can I see manta rays?
Mantas show up around the Kohala coast year-round, though sightings are never guaranteed since these are wild animals. The dedicated manta trip is your best shot at a close encounter.
Is this good for beginners or kids?
Certified beginner divers do well here thanks to the calm pace and tiny groups. The manta dive and snorkel is the most family-friendly option, since a non-diving family member can snorkel alongside the dive.
