Reviews: Ko Samet: 5 or 6 Islands Snorkeling Tour with Lunch Option
Guest User2026-02-22
We were contacted in advance via WhatsApp, and soon met up with the staff at the meeting point on the beach. They took lots of photos for us to download after the tour. For lunch we had Khao Pad and lots of fruit. While there are many remote island tours in Thailand, Samet is not particularly beautiful! However, we were able to see many fish while snorkeling. It's close to Bangkok, so I think it's a good place for a weekend trip.

Reviews: Available today! 1-day tour to Koh Larn with 22-person small group for snorkeling in Pattaya, departure from Bangkok possible
Guest User2026-04-29
Yesterday, our booked leisure package included a classic Thai lunch and a paddleboarding experience. The tour guide was exceptionally attentive, not only coordinating everything enthusiastically but also proactively sharing many fun tips for the island, allowing us to make the most of our free time. The complimentary paddleboarding was a lot of fun. The included Thai lunch was decent, and the dining environment was acceptable. The itinerary was well-planned, with ample free time on the island. The tour guide carefully reminded us of safety precautions throughout, making this trip relaxing and worry-free. It's perfect for friends or small family groups—highly recommended!

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 to the open sea | Explore uninhabited islands | Snorkeling/Fishing + English guide | 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.

Reviews: Finding Nemo: Pattaya Snorkeling Tour
Guest User2026-06-21
Great value and fun! The coach is attentive and includes photos📸 Recommended! This time I took the Pattaya snorkeling day trip and the overall experience was much better than expected. Let’s start with the advantages: 1. The coach is very attentive! Safety tips and snorkeling techniques will be explained in detail before departure. Special care for group members who do not know how to swim 2. Water quality is clearer than imagined! Although Pattaya is not known for its clear water, the snorkeling spot chosen by this group (near Koh Larn/Koh Sak) has good visibility, with lots of coral and tropical fish, as well as Nemo clownfish! 3. Includes beautiful photo service! The coach will use a waterproof camera to help us take pictures, and will also take the initiative to lure the fish over for easy shooting. After the event, he will send us all the photos for free. This is really a plus! 4. Extremely good value for money! The price includes hotel transfers, snorkeling gear, and a few hours of fun all day, which is definitely worth the quality. 5. The boatman and staff are enthusiastic, the atmosphere is relaxed and pleasant, and ice water is provided to cool on board after playing on the sea! A little reminder: · It is recommended to wear a swimsuit inside before departure, as space to change after boarding is more limited. · If you are afraid of sea sick waves, remember to take dizziness pills in advance because you have to go to the open sea snorkeling point. summary: If you are thinking of coming to Pattaya for water activities and don’t want to join some too expensive luxury tours, this snorkeling tour is definitely a high quality choice! The arrangement is smooth, and there are beautiful photos to keep!
