Reviews: MR. TU's Samui Island deep sea fishing one-day tour (shared/private boat options) - professional fishing boat with fresh catch processing
Guest User2026-07-04
We had a wonderful time. Someone caught a shark, someone a very small fish, someone a little bigger. They prepared a delicious lunch for us. And they helped us with the catch in every way possible. We stopped for a swim in the sea. I went with my 10-year-old son. At first, he was very upset because he couldn't catch anything, but then when he caught one, he was incredibly happy. We've been talking about this trip for a long time and will definitely do it again when we're here again.

It was so much fun! I’d never gone fishing in the sea before. It was such a great experience.

Reviews: Koh Samui one-day tour[Off-road Vehicle Around the Island | Island Sightseeing | Optional Elephant Encounter or Kayaking]

As a Chinese person, this is my first trip to Koh Samui since the pandemic. I traveled here for three consecutive years in 2016, 2017, and 2018, and back then there were so many Chinese tourists. I just want to say that the island tour was incredibly enjoyable. My wife also thought the guide and the SUV experience were fantastic. We even had lunch and danced with some foreign friends! Unforgettable memories. I hope more Chinese tourists will come to visit. Although there are many small travel agencies near the hotel offering island tours or boat trips, I recommend booking directly through Ctrip (safe, reliable, and they speak Chinese). You can just wait in the hotel lobby the next day…! In short, Thailand is safe, and I hope you'll have the chance to come and enjoy its beautiful scenery.

The pigs simply stole our hearts. We never would have thought we loved pigs so much. 😁. Definitely a must-see!

Reviews: 1-day tour to Mu Ko Ang Thong National Marine Park from Koh Samui [snorkeling/lunch/transfer/kayaking]
Guest User2026-09-08
The route matched the description. The excursion itself was wonderful. I highly recommend it. We were with the Funny Day team. They're great guys, but there was one major drawback I didn't like. On the way back from the archipelago to Koh Samui, we ran out of gas. Oh well, it happens. We first took some gas from a boat traveling alongside, but it wasn't enough. Then we waited for a second boat to bring gas and pick up some of the people. And it seemed like everything should go smoothly from there, but no! The new boat also ran out of gas 100 meters from the beach. And we waited for a third boat. They need to fix this urgently and bring extra gas. Otherwise, the excursion itself, the views, the snorkeling, and the kayaking were amazing. The views from the observation deck are incredibly beautiful, but the climb is very difficult and is best done in sneakers.

Incredible tour!! Mr. Tu is the best. Everything was exactly as described, the guide and accompanying staff were incredibly cool. Water and cola were offered at every stage, and beer was available for an extra fee. I really enjoyed it, I highly recommend it.
