Reviews: Pure play experience with scuba diving, snorkeling and sea walking at Koh Larn in Pattaya, Thailand, including hotel transfer
Guest User2026-08-14
Almost everyone was Chinese, but they were full of energy and it was quite fun. We sang songs on the boat~ In particular, our guide, Auntie lek11, took special care of us Koreans, so even though the main guide was Chinese, I didn't feel left out and had a really warm and fun time. Thank you!! Also, the boat driver who played music perfectly, just like a DJ, was seriously the best driver👍👍 The itinerary was a bit like a factory schedule, but it was fast and systematic, took great photos, and the hygiene wasn't bad, so it was great to have fun. It was a truly beautiful experience!! I recommend it to Koreans hehe. You really get treated well.

Reviews: Diving experience in Pattaya, Thailand - beginner scuba diving with no certification required - professional boat diving - 1v1 coach
Guest User2026-09-19
The first dive was good, educational, but the guy was given fish food twice, and I wasn't given any. The second time, they took us deeper, and I saw a turtle and lots of big fish, but the guy was taken really far away, and they got lost. When everyone had already left and the boat was about to sail, he wasn't there yet, and I was really scared. Then we swam to them, and the guy said he'd only been taken to see sea urchins and small fish; he didn't see anything interesting, which was really sad. The food on the boat was decent, and we had one meal, and free drinks. They refused to take us back, except to the hotel, and since it wasn't on our way, we had to drive ourselves. You can also buy the same diving experience from the locals on Koh Larn Island, but we were also disappointed that we took a ferry instead of a boat; the ride was long. The ferry costs only 40 baht, if you buy it yourself, then you can also walk around the island and stay there for a swim, but here from point to point, diving takes an hour, and stupidity for about 4 hours. Vague feelings
