Manta rays feel unreal at sunset. I love the close-up swim with giant oceanic mantas and the laid-back KIBOU boat ride that ends with hot cocoa. The only real drawback is the rays are wild, so sightings can’t be guaranteed.

From Honokohau Small Boat Harbor (Slip A17), the trip runs about 2 hours and starts with a proper safety briefing. The crew helps you get set up on the water, then you snorkel in Hawaiian waters from a floating mat while the captain picks the best spot based on ocean conditions.

One more thing to plan for: you’ll likely feel the cool after your snorkel. Wetsuits are available to rent ($10 per adult, $5 per child), and you’ll want a towel and a warm layer ready for the ride back.

Key takeaways before you go

• Captain picks the snorkel spot based on current ocean conditions, not guesswork.
• Safety briefing matters: you’ll learn how to interact with wild manta rays before getting in.
• Snorkel gear is included, plus fins and snorkel equipment, with prescription goggles available.
• Expect a floating mat setup for the water time, not a long swim with constant drifting.
• Hot cocoa comes after snorkeling, which feels like a small win after you’re done getting your “mantas close” fix.
• Rays aren’t guaranteed, but if you don’t see them, you’ll get the next available tour at no added charge.

KIBOU from Honokohau Harbor: where the manta hunt starts

This tour is based out of Honokohau Small Boat Harbor, and you’ll board the KIBOU at Slip A17. It’s about a five-minute drive north of Kailua-Kona, and parking is free, which is handy because you’ll want an easy start when you’re juggling towels, snacks, and timing.

Before you head out, you’ll fill out a waiver form. Then you’ll get on board with the essentials handled for you: there’s a bathroom on the boat, and you can change there too. That matters because once you’re in swim mode, you don’t want to scramble for basics.

Sunset vs moonlight: picking the right time window

You get two main vibes here: a sunset snorkel on the earlier departure, or a later moonlight tour. The sunset departure is the early one, and the moonlight option is the last departure.

In plain terms, sunset tends to feel like the most “classic” outing: you cruise out, then watch the sky do its thing before you’re in the water. The moonlight tour trades that warm glow for a more nighttime feel, and it can be especially memorable if you like the ocean under low light.

The captain’s plan: why the right spot changes everything

A big part of your experience is that the captain doesn’t send you to one fixed location no matter what. The captain determines the best manta snorkel spot based on current ocean conditions.

On the water, that means you’re anchored and then guided to the floating mat where you’ll snorkel. You’re not left to figure it out alone. The crew’s job is to get you positioned and confident so you can focus on what’s under you.

And yes, currents and conditions can affect what you see. That’s one reason sightings can’t be guaranteed. It’s also why the captain’s real-time decisions matter more than any marketing promise.

Safety briefing and getting it right in the water

Before you snorkel, you’ll get a safety briefing and learn how to interact with these wild animals. That training isn’t just a formality. If you listen closely and follow instructions, you’re more likely to have a calm, smooth time in the water.

I like this approach because it sets expectations: you’re not controlling wildlife, and you’re not treating this like a theme-park exhibit. You’re in their world, so your job is to stay focused, follow the crew’s guidance, and move in a way that doesn’t create chaos.

One practical tip: pay attention to how you’re supposed to handle yourself while snorkeling. Some people get cold and distracted and then don’t follow guidance as well as they could. If you want the best experience, treat the briefing like it’s part of the adventure, not a chore.

Snorkeling with giant oceanic manta rays up close

Once you’re anchored, the crew helps you settle into the snorkel routine from the floating mat. This setup is easier than it sounds because it gives you a stable base while you scan the water below.

The experience goal is to get up close and personal with giant oceanic manta rays in Hawaiian waters. In a good session, you might see multiple rays at once, including rays that come surprisingly near you.

You’ll also have time to spot other ocean life while you’re snorkeling. Underwater viewing support matters too, and in the best outings there’s lighting underwater, which can help you see rays up close. It makes a real difference when the water turns dark or when the rays are gliding from one angle to another.

Gear and comfort: what you’re provided (and what you might need)

Snorkel and fins are included, and prescription goggles are available if you need them. That removes a lot of hassle, especially if you’re already packing for a Hawaii trip.

Still, plan for temperature. If you’re someone who gets cold easily (it happens to a lot of people on the water), consider renting a wetsuit. Rental cost is straightforward: $10 per adult and $5 per child. It can extend your comfort so you can actually enjoy the time instead of rushing through it.

What I’d pack for comfort:

• Swimwear you can wear right away
• A towel (you’ll want it for the return)
• A warm layer or sweatshirt for after snorkeling
• A change of clothes for the ride back

Sunset boat ride details: snacks, beverages, and the crew vibe

You spend time cruising out and back, watching the ocean and the sky. During that ride, the tour includes water, snacks, and beverages. The vibe tends to be friendly and practical, because you’ll be boarding an ocean trip where the details matter.

Some guides also help keep the mood light while you’re waiting to go in. I’ve seen crews run the trip with a mix of safety and humor, and it makes the whole thing feel less like you’re “observing wildlife” and more like you’re sharing the moment with the ocean.

Depending on the day, you might hear familiar names among the crew. People describe guides like Diego, Tamre, Scott, and Brice, and captains like Trevor. Whoever’s on your trip, the common thread is clear: they try to make sure you feel set up and supported from the deck to the mat.

Hot cocoa on the return: the sweet landing after the snorkel

The hot cocoa part is simple but smart. You’ll get hot cocoa on your way back to the harbor after snorkeling, which is exactly when you want something warm.

This is also why I think the tour’s structure works: you snorkel first, then you recover. You don’t have to juggle hot drinks while you’re in the water, and you don’t have to wait forever to feel comfortable again.

Alcohol rules you should actually care about

Alcohol is allowed on this tour, but only after snorkeling. Also, no glass bottles are allowed.

That rule matters because you’re on a boat, in and around water, with gear and movement. If you want to bring a drink, plan it for the return portion only, and bring it in whatever non-glass format fits the rules.

Price and value: is $125 really fair for 2 hours?

At $125 per person for a 2-hour experience, this isn’t a “budget snack” activity. It’s priced as a premium wildlife encounter, with real field support: boat tour, live guide, snorkel and fins, hot cocoa, and onboard bathroom access.

What makes it feel more like good value is the way the tour handles the biggest uncertainty. Manta rays are wild animals, so sightings can’t be guaranteed. If there aren’t manta rays during your outing, you’re offered the next available tour at no additional charge. That turns “chance” into “second try,” which is how you protect your money and your time.

You’re also getting more than one moment of the trip. You’re not only paying for the swim. You’re paying for the guided setup, the captain’s spot selection, the sunset or moonlight cruise, and the comfort elements like warm hot cocoa at the end.

Who should book this manta ray snorkeling tour?

This tour is a great fit if you:

• Want a close-up wildlife encounter without doing it on your own
• Like structured guidance before you get in the water
• Are comfortable snorkeling from a mat and following crew instructions
• Want the sunset or nighttime atmosphere of Kona’s western shoreline

It may not be the right choice if you have mobility impairments. The tour info notes it’s not suitable for people with mobility impairments and also flags wheelchair users. At the same time, the activity is marked wheelchair accessible, so if accessibility is a concern for you, you should contact the operator directly before booking to clarify what can realistically work for your situation.

Quick planning checklist for a smoother trip

If you want fewer little headaches, do this before you leave your hotel:

• Bring swimwear plus a change of clothes
• Pack a towel and a warm layer for after
• Bring/confirm what you want for eyewear (prescription goggles are available)
• Consider renting a wetsuit if you run cold ($10 adult, $5 child)
• Avoid glass items (no glass objects)
• Expect to sign a waiver

Also, double-check which departure you’re booking. Sunset snorkel means an earlier start; moonlight means the later departure.

Should you book Kailua-Kona manta ray snorkeling with hot cocoa?

My take: if manta rays are on your Big Island bucket list, this is one of the more well-rounded ways to chase them. You get the boat ride, captain-led spot selection, real guidance in the water, and then a warm landing with hot cocoa back at the harbor.

Book it if you’re comfortable snorkeling, you follow instructions, and you’re ready for the one unavoidable truth: manta sightings depend on wild conditions. When they do show up, the payoff is the kind of moment you’ll remember in detail, not just as a vague “we saw something cool.”

Skip it if you know you won’t handle cold water or if mobility limitations make getting in and out of the water difficult. And if you’re uncertain about accessibility, contact the provider early so you’re not guessing.
