Snorkel after dark off Kailua-Kona with an experienced crew and look for giant manta rays at the site with the best prospects.

About this tour

Set out after dark for a chance to see giant manta rays glide through the waters off Kailua-Kona. With more than 12 years of experience, this family-run crew pairs careful safety practices with knowledgeable guides for an unforgettable ocean encounter. This 120-minute Kailua-Kona manta ray snorkel tour may visit the northern site near the airport or head south to Keauhou, depending on where sightings look most promising. A Red Cross-licensed in-water guide and lifeguard leads the experience, and snorkeling equipment and a wetsuit are provided. Manta rays are wild animals, so sightings cannot be guaranteed. If no mantas appear, you may request a different-night rebooking for a fee, subject to availability; refunds are not offered. Participants need basic swimming skills, prior snorkeling experience, the ability to climb a boat ladder independently, and enough English to understand safety instructions. Check in at the north side of Honokohau Small Boat Harbor, and confirm your arrival time with the provider. Book your Kailua-Kona manta ray snorkel tour for a memorable night on the water.

How this score is calculated

This score is based on one provider. Viator rates it 4.58 from 142 reviews. We place that rating among all Viator ratings and weight it by its review count. If the tour is found on another provider later, both ratings are combined.

How the score works and rating distribution in Big Island of Hawaii
  • Each provider rating is turned into a percentile: the share of that provider's ratings it beats, weighted by review counts.
  • Listings on different providers are combined in proportion to their review counts.
  • Tours with few reviews are pulled toward the average until more reviews come in, so a handful of perfect reviews can't top the list.
  • The result is shown from 0 to 10: this tour scores 5.7.
