Choosing a Kona Manta Night by Harbor, Boat and Guarantee
A manta ray night snorkel on the Big Island is a west-side evening, so I compare listings on three lines: the harbor named, the size and style of the boat, and what happens if no mantas show.
According to the Hawaii Guide manta ray night snorkel page, Kona manta ray night snorkel boats leave from west-side harbors such as Keauhou Bay and Honokōhau Harbor around sunset, and the snorkelers float at the surface holding a lit board that draws plankton.
I write from Hilo, and to me the Kona coast at dusk is a different island. One June evening in 2021 I was on the shore, not on a boat. From the small park at Keauhou Bay I watched the last pink fade off the water and the first boat lights blink on offshore. A cool breeze came down from the hills smelling of plumeria and diesel. Out past the point the lights glowed blue green on the surface, and I could hear laughter carrying across the dark water.
Big Island Manta Ray Night Snorkel: Repeat-Trip Guarantee
The listing says you get a free next trip if no mantas are seen. Its summary does not name the departure harbor, the group size, or whether gear and wetsuits are included, so I would ask about all three, along with how the guarantee is redeemed, before paying.
I would pick Big Island Manta Ray Night Snorkel for travelers who have more than one free evening on the Kona side and want a sighting guarantee that covers a repeat trip. Skip this listing if the manta night falls on your last evening on the island, because a free next trip only has value when you are still around to use it.
Big Island Manta Ray Night Snorkel
From $94 · Price checked: Oct 2026
Best for: Travellers wanting a manta ray night snorkel backed by a sighting guarantee that covers a repeat trip.
Not for: Anyone wanting detail before booking, as the listing does not state group size, gear, wetsuits or departure point.
A two and a half hour manta ray night snorkel, with a free next trip if no mantas are seen. Confirm the departure harbour, group size, whether gear and wetsuits are included and how the guarantee is redeemed.

Short, Small-Group Manta Snorkels from Keauhou and South Kona
For a short manta outing on a smaller boat, I would look at the two listings in this section first.
Site matters as much as harbor. Two well-known Kona manta sites are Manta Village off Keauhou and Manta Heaven near the airport, and each operator decides which site it uses that night. That point comes from the Hawaii Guide page cited above. If you are weighing boat size, my small-group versus standard boat comparison sets the two formats side by side.
Manta Magic: Small-Group Manta Ray Night Snorkel in Kailua Kona
The listing says this trip departs from Keauhou Harbour, with a short ride out to Manta Village and a lightboard with flotation.
I steer travelers staying around Keauhou or Kailua-Kona who want a brief, small-group night to Manta Magic. It is a poor fit if you want a sunset sail as part of the evening, since the listing describes a short snorkel trip and not a cruise.
Manta Magic: Small-Group Manta Ray Night Snorkel in Kailua Kona
From $145 · Price checked: Oct 2026
Best for: Travellers wanting a short manta ray snorkel with a maximum of 12 passengers and a five-minute boat ride.
Not for: Those wanting a sunset sail or longer evening, as this is a one-hour trip focused on the snorkel.
A one-hour small-group manta ray night snorkel from Keauhou Harbour, with a five-minute ride to Manta Village and a lightboard with flotation. Confirm whether wetsuits and gear are included, and the policy if no mantas appear.

Night Manta Ray Experience off South Kona
The listing says this night snorkel runs off the South Kona coast, with in-water guides after a short boat ride. It does not name the departure harbor, and it does not mention wetsuits, gear or the policy if no mantas appear.
I would pick Night Manta Ray Experience for travelers staying south of Kailua-Kona who value a very short ride to the site. Choose a guaranteed listing instead if written no-sighting terms matter to you, because this summary does not mention any.
Night Manta Ray Experience
From $146.41 · Price checked: Oct 2026
Best for: Travellers wanting a manta ray night snorkel off South Kona with a very short boat ride to the site.
Not for: Those wanting a sunset sail or onboard extras, as the listing mentions only the short ride and guided snorkel.
A 90-minute night snorkel with manta rays off the South Kona coast, with in-water guides after a short boat ride. Confirm the departure harbour, whether wetsuits and gear are included and the policy if no mantas appear.

Sunset Catamaran or Large Vessel at Manta Village
The draw is the feeding itself. According to the Wikipedia manta ray entry, reef mantas feed on plankton, and night dives with lights let viewers see mantas feeding on plankton drawn to the light.
Sunset and Manta Ray Snorkel Adventure
The listing says this outing uses a catamaran and combines a sunset sail with a guided manta ray snorkel, with gear, wetsuits and non-alcoholic drinks included.
I would pick Sunset and Manta Ray Snorkel Adventure for couples or families who want the sail and the snorkel in one outing without packing their own gear. If the sunset is the real priority, my Kona sunset cruises page covers sail-focused options.
Sunset and Manta Ray Snorkel Adventure
From $154.51 · Price checked: Oct 2026
Best for: Travellers wanting a sunset sail and a manta ray night snorkel in one outing, with wetsuits and drinks provided.
Not for: Those who only want the manta snorkel in a short trip, as this adds a sunset sail on a larger catamaran.
A 135-minute trip on a 50-foot catamaran, combining a sunset sail with a guided manta ray snorkel, with gear, wetsuits and non-alcoholic drinks included. Confirm the departure harbour and the policy if no mantas appear.

Kona Manta Ray Night Snorkel at Manta Village
The listing says this trip visits Manta Village in a large-vessel format, with a free return if no mantas are seen.
I steer travelers with flexible plans and a few Kona-side nights to Kona Manta Ray Night Snorkel. Skip this listing if you picture a quiet, small-boat evening, because the listing describes a large-vessel format.
Kona Manta Ray Night Snorkel, 85-95% Sighting Rate
From $141.03 · Price checked: Oct 2026
Best for: Travellers with flexible plans who value a stated 85 to 95% manta sighting rate and a free return option.
Not for: Those leaving Kona within days, as the free return if no mantas appear is within 7 days and space available.
A 90-minute manta ray night snorkel at Manta Village, Kona, in a large-vessel format, with a free return within 7 days if no mantas are seen. Confirm included gear, wetsuits and the departure harbour.

Practical Tips for Getting a Kona Manta Night Right
I would put the snorkel early in a Kona-side stay, confirm gear and wetsuits line by line, and pack a warm layer.
Manta ray sightings on any one night are not guaranteed, and operators handle weather cancellations and no-show nights differently. My advice: do not leave a weather-dependent tour to the last day of the trip, with no night to rebook.
For questions about swimming ability, health or water safety, I point you to the operator's listing and official advisories, not to me.
A manta night is a poor fit if you are not comfortable floating at the surface after dark. In that case a sunset sail on its own may suit you better, and my Big Island snorkeling page covers daytime reef trips.
What to Check Before Booking a Kona Manta Snorkel
Before you pay, I would run through a short check: harbor, site, no-sighting terms, inclusions, and how the evening fits around the rest of your day.
- Check the departure town or harbor named in the listing, because Kona-side and Hilo-side departures are far apart.
- Ask which manta site the operator plans to use, since the operator decides that on the night.
- Read the no-sighting terms and write down how a free trip or return is redeemed.
- Confirm wetsuits and gear against the card, and assume nothing the listing does not mention.
- Treat the drive between the Kona and Hilo sides as part of the day when you plan a tour on the other coast.
Booking a Hilo-side tour and a Kona-side evening activity on the same day without checking the drive is a mistake that can leave you rushing to a harbor at dusk.

Frequently Asked Questions
Will I see mantas on a Kona night snorkel?
No listing can promise mantas, and sightings on any one night are not guaranteed. Two listings on this page describe a free next trip or free return when none are seen, so compare those terms first.
Which harbor do Kona manta boats leave from?
The harbor depends on the listing, and Manta Magic is the one here that names Keauhou Harbour in its summary.
Are wetsuits included on Kona manta snorkels?
Sunset and Manta Ray Snorkel Adventure lists gear and wetsuits as included. The other summaries do not mention wetsuits, so send the operator a message if you need one.
Can I fit a Hilo-side day and a Kona manta snorkel into one day?
You can try, but you should plan the cross-island drive as part of the day and check it on a map first. A missed sunset departure may not count as a weather cancellation under the listing's terms.
What should I bring for an evening on the Kona coast?
Pack a dry warm layer and a towel for after the snorkel, because the breeze off the hills turns cool after dark.
