★★★★★★★★★★5.0 · 2,212 reviews · 1 hour 20 minutes (approx.) · from $49

Review of Kona’s affordable manta ray night snorkel, with small groups, safety details, timing, value, and practical booking advice.

“I was fairly skeptical before we got to the water. Having in mind that mantas are actually wild animals… but I guess Keyo, Taco and Max knew exactly what they were doing (or maybe we just got lucky?). We got to see a small pack of them SO CLOSE! Great experience from booking to completion. Good instructions on a meeting spot. If you have a wet suit- bring yours everything else you’ll get there.”

“The crew was great, put we didn’t see any Manta Ray. The sea was rough and we floated in the cold water for about an hour. Sam the deck hand offered another trip,but NO vouchers were issued to any participants or refund. The Captain of the boat bragged on how he has the best lights out of any crew(boat) and still saw not even 1 Manta Ray! Several people got sea sick as well. Including my wife.. This was the worst part of our vacation.. Would I do it again?”

★★★★★★★★★★5.0 · 308 reviews · 7 hours · from $125

Review of Krabi’s 4-Island Sunset Cruise, with snorkeling, Thai buffet, paddleboards, sunset views, and a glowing plankton swim.

“My daughter and I had a wonderful day on the boat. From the start, we felt well taken care of by native English-speakers, which made everything clear and easy to follow - something I had struggled with on other activities. We were taken by longboat from Ao Nang to a bigger boat, and that’s where the adventure began. It was our first time snorkeling and we were amazed by the colorful fish. Michael provides high-quality equipment, explains everything clearly, and the team keeps a close eye on everyone, offering help immediately if needed. There were also paddle boards - learning to stand up was a challenge my daughter happily accepted…”
