Troy, Kate, Raj, Joe, and the rest of the crew have built a serious reputation for making people feel like family on the water. Reviewers consistently praise the team's warmth and professionalism, and it's clear the guides genuinely love what they do. First-timers and experienced divers alike feel looked after, with patient, knowledgeable instruction and a relaxed atmosphere throughout. The manta ray night snorkel is the star of the show, described by multiple guests as one of the most magical experiences of their lives. But the offerings go well beyond that, from dolphin-spotting excursions to discovery dives for kids and full scuba trips with multiple stops. The team goes the extra mile with thoughtful touches like food, drinks, GoPro footage, and warm towels after the dive. With near-perfect ratings across a large number of reviews and repeat visitors showing up regularly, this operation clearly delivers. If you're on the Big Island and looking for a water adventure, the manta ray trip alone is worth booking around.
Cannot say enough good things about our experience with Kona Ocean Adventures. We did two of their experiences: snorkeling and the manta ray observation at night. Our guide, Kate, was incredibly friendly and knowledgeable about the area. Our two captains, Raj and Troy, got us to our destination safely and made sure we were taken care of. After a cold night swimming, they had hot chocolate prepared for us. After snorkeling, they had a charcuterie board prepared for us as well. There were plenty of drinks available to us. They provided towels and were very attentive to our needs. I would recommend this to anyone.
