Kona Manta Ray Snorkel Tour with Optional Sunset or Moonlight

The heart of this Kona trip is a close look at manta rays feeding beneath a lighted float. You hold on at the surface while plankton gathers below, and the rays glide through the beams. Some outings have seen four rays at once, while one had about ten. Sightings are never guaranteed, but if none appear, your next trip is free.

I like two things in particular: the float-and-watch setup, which gives you a stable place to hold while the rays come near, and the warm cocoa afterward, a welcome touch after time in the ocean at night. You can also choose a ride-along ticket if you want the boat trip without snorkeling.

One point needs checking before you book: the package names include Sunset and Moonlight, but the tour details say a sunset cruise is not included. Departure times are listed as 8:00, 8:30, and 9:00 p.m., so confirm exactly what your chosen package includes and do not assume you will be on the water at sunset.

What to know before you go

1 / 8

• A lighted float brings the action close: Plankton gathers around the float’s lights, drawing manta rays into view as you hold on at the surface.
• Choose the right swimming category: Confident swimmers can book any departure. Beginner snorkelers are limited to Sunset and Twilight options, not Late Night.
• Manta sightings vary: Groups have seen one ray stay for 20 minutes, four at once, or around ten. If none appear, the operator offers a free rebooking.
• Bring motion-sickness medicine if you need it: The operator recommends taking it two hours before departure if you are prone to seasickness.
• Wetsuits cost extra: Masks and a viewing float are included, but wetsuits are available for a small additional fee.
• Plan for a night outing, not a sunset cruise: The listed departure slots are 8:00, 8:30, and 9:00 p.m. Check your package details for the actual schedule.

At the harbor, the night begins

The tour meets at Iruka Hawaii Dolphin and Manta Tours, 74-380 Kealakehe Pkwy, Kailua-Kona, at Honokohau Small Boat Harbor. You choose a departure time when booking, then return to the same address. Arrive 15 minutes early; late arrivals and no-shows are not refunded.

The outing lasts about two hours, including the boat ride, time with the manta rays, and return to the harbor. The exact schedule can shift with weather and traffic, so treat the return times as estimates tied to your selected departure. The listed return slots are 10:00, 10:30, and 11:00 p.m.

There is a small discrepancy worth sorting out when booking. The tour description mentions sunsets and sunset cruises, but the included-items list says the sunset cruise is not included, and the available departure slots are all at night. If seeing the sun go down from the boat matters to you, ask the operator what the Sunset package means for your date and time.

The boat is KIBOU, and the listed group size is two to 30 people. An onboard bathroom is included, which is useful on a night trip, especially if you are bringing children. Round-trip transport is not part of the standard fare, though a pickup service from select North Kona locations can be requested for an additional $50 per person.

The boat ride to Manta Ray Heaven

The boat heads along the Big Island’s western coast toward the manta viewing area, described as Manta Ray Heaven. On the way, you may spot dolphins, and whales are possible in season. Wildlife sightings are a bonus, not a promise, so think of this part as the journey to the main event rather than a separate wildlife tour.

If you enjoy being on the ocean after dark, the ride adds atmosphere to the trip. Sunset and moonlight can frame the coast, though conditions and timing vary. The boat may feel choppy, and if motion sickness is a concern, take the operator’s advice and use travel-sickness tablets two hours before the activity.

The crew provides snorkeling masks and a floating manta-viewing mat. The lighted float draws plankton, which in turn attracts manta rays. Rather than swimming around freely, you hold onto the float and watch from the surface as the rays move below and around it. This setup can make the encounter more manageable, but it still requires you to stay calm in open water at night and follow crew instructions.

Holding the float while manta rays pass

The main event is quiet and close: you float at the surface and watch for manta rays feeding in the light. Their movements can bring them near the viewing float, sometimes close enough to feel startling. The encounter depends on wildlife, so you may see several rays, one, or none on a particular outing.

Past sightings have varied widely. One group watched a large female called LouLou Ray remain nearby for about 20 minutes. Other outings have seen four rays together or around ten. These examples show what is possible, not what you should expect on a given night.

The free rebooking offer helps soften the risk of a no-show by the rays. It is still worth thinking about your schedule: a second attempt only helps if you have time to take it. If you are on the island for just one night, the offer may have less practical value than it does for someone with flexible plans.

This is a wildlife encounter, not a performance. The rays choose where to swim, and the operator asks you not to feed marine animals, walk on coral, or do anything that could harm the ecosystem. Keep your movements controlled and follow the crew’s directions to protect both the animals and the experience for everyone in the water.

Picking a departure that suits your comfort level

The tour asks you to choose a ticket that matches your swimming ability. A Confident Swimmer ticket is for people comfortable swimming in the open ocean at night, able to stay calm while floating and follow crew instructions. It is available for all three nightly departures.

The Beginner Snorkeler option is for people with little or no snorkeling experience, or those who are uneasy in open water at night. It is available on Sunset and Twilight departures, but not Late Night. The operator caps Beginner Snorkeler and Ride-Along tickets at 15 people total per tour to maintain the stated crew-to-guest ratio.

That distinction matters. Holding a float can make the activity feel less demanding than swimming around independently, and one family with non-swimmers completed the outing while holding on. But the setting is still the open ocean after dark. Be honest about your comfort in water, and do not book Late Night if you are not a confident swimmer.

If someone in your party would rather stay aboard, a discounted Ride Along ticket is available. This can make the outing workable for a mixed group, but those tickets count toward the cap alongside beginner tickets. Children aged zero to two are free, children aged 0 to 11 must be with a paying adult, and those aged 12 or older pay the adult rate.

Warmth, snacks, and what to bring

Masks, the floating viewing mat, snacks, and refreshments are included. Warm cocoa is served after the snorkel, a practical comfort rather than a grand meal. You can bring your own food and drinks, and alcohol is allowed if it is not in a glass bottle.

Bring swimwear, a towel, and sunscreen. A wetsuit is not included, but one is available for a small fee. Several families chose to rent one and found it helped them stay warm in the water. One family reported paying $10 per person, though the current fee may differ, so confirm the price before you go.

The operator notes that menus can change with season and ingredient availability. Since the trip is only around two hours and snacks are light, eat beforehand if you need a proper meal. If you have a sensitive stomach, consider the motion-sickness advice before boarding rather than waiting until the boat is underway.

Is the price worth it?

The advertised starting prices vary: the package options are shown from $129.75, while the experience summary gives a starting price of $149.25. Check the date, departure, and package at checkout for the fare that applies to you. The price includes the boat trip, snorkeling, mask, viewing float, snacks, refreshments, and the crew’s guidance. Wetsuits and transport are extra.

For a night wildlife outing, that bundle has real value if you want the organized setup and gear provided. The float and lights are central to how the encounter works, and the onboard bathroom is a useful inclusion. The no-manta rebooking offer also gives you another chance if your first trip has no sightings, though it cannot guarantee that you will see rays on a later date.

On the other hand, the base price is not the full cost if you need a wetsuit or paid transport. Nor should you pay expecting a guaranteed sunset cruise or a guaranteed number of rays. You are paying for a guided trip to a known manta viewing area and the chance to observe wild animals at close range.

The tour suits you best if you are comfortable with nighttime ocean conditions, curious about marine life, and willing to accept some uncertainty. Families can take part, including children, but parents should think carefully about each child’s swimming confidence and comfort in the water. A ride-along option helps if someone wants to join the boat without snorkeling.

Should you book the Kona manta snorkel?

Book it if seeing manta rays in their natural habitat is high on your Big Island list and you are comfortable with the open ocean at night. The lighted float, provided mask, onboard bathroom, snacks, and free rebooking if no manta rays appear make this a well-supported way to try.

Pause before booking if you are sensitive to motion, unsure about swimming at night, or expecting a guaranteed sunset cruise. Check the meaning of the Sunset package, confirm your departure time and any extra costs, and choose the swimming category that honestly fits you. If those details suit your plans, this is a memorable wildlife outing with a clear payoff when the rays arrive.
