Reviews: Ko Samet: 5 or 6 Islands Snorkeling Tour with Lunch Option
Guest User2026-08-09
I chose a service package, booked it, paid, and a couple of hours later they contacted me via messenger (the one I chose) and said they'd pick me up half an hour before the service started. The bike arrived, they took me to the pier, gave me a wristband, and about 10 minutes later I boarded the boat and sped off to the island. The boat staff were excellent, always positive. We looked at the fish, fed them, and if anyone had any problems with their mask and snorkel, they were there to help. Then we went ashore, took a look around, took some photos, and came back down with some fruit already cut up. Overall, it was a blast. If I ever go to Samet again, I'll snorkel with this team.

Reviews: Pattaya Beach Parasailing Experience [Pattaya Beach Parachute/Parasailing [Mood Elevation/360-Degree Panoramic View/Speedboating Transfer]]
Guest User2026-06-23
It was a novel experience, with the flight lasting about 2 minutes. The only downside was that the shuttle boat took you from the beach to the sea towing base, not from the pier; so on the way there, the shuttle boat stopped quite far away, making it dangerous to walk across the beach as the water was knee-deep. After feedback from the people there, the shuttle boat stopped much closer on the return trip.

Reviews: Pattaya 1-day tour | Explore uninhabited island | Snorkeling / fishing | Sunset party
Guest User2026-06-02
This experience was absolutely amazing. Everyone on the yacht, from the staff to the crew, was incredibly impressed. Afu, who was on the yacht, had been studying Chinese for three years, but you couldn't tell he'd only studied for three years. You'd almost think he was Chinese because his Chinese was so fluent. He provided such attentive service, even though my sister and I were the only Chinese people on the yacht. I really wanted to tip him, but unfortunately, I missed the chance. If anyone books this trip because of my honest review, please say hello to Afu for me. He's a truly kind, bright-eyed, and simple young man. Spending a day with him made me realize how simple, genuine, and happy people can be.
