Reviews: Depart from Koh Samui: Private Charter Boat Tour [Snorkeling + Island Hopping]|Longtail Boat (Optional)|Speedboating, etc.
Guest User2026-10-15
Private longtail trip to Koh Mudsum (Pig Island) and Koh Tan with our two boys. Boat and driver were great: kind, careful and on time, and the weather cleared up nicely. Good value for a private boat. One thing to improve: we had no explanation of what was on each island or what to expect, so a short briefing at the start would make it even better. Bring cash for the ฿50 pp entrance fee at Koh Mudsum.

Reviews: Samui Boat Charter, Private Speedboat Charter, Angthong National Marine Park
Guest User2025-12-24
The boat was well equipped and maintained. Hong, our guide, was wonderful and super engaging and playful with the younger kids in our family. Nut and Film - our other crew members - were equally attentive and friendly. Overall we had a fantastic and well executed day! It started with picking us up at the beachfront of our hotel, then to the Angthong Marine Park (we visited first to avoid the large crowds so that the climb up and down to the Emerald Lagoon wasn’t rushed for our little hikers), then to a spot north of the park to privately snorkel, followed by lunch (we preordered so that the food was ready for us when we arrived), next to a private beach cove (which unfortunately was covered with plastic rubbish but our team quickly cleaned the beach with help from us) and then back to the beachfront of our hotel in Bophut. The experience was fully enjoyed by all in our family, from the youngest to the oldest. I highly recommend this company - booking was a breeze and communication up to our tour and throughout our experience was impeccable.

Reviews: Departing from Koh Samui: Koh Madsum & Tean Island snorkeling experience | dolphin chasing tour upgrade available
Guest User2026-11-09
It was an absolutely fantastic experience on Koh Samui that you definitely shouldn't miss! Since we were there during the rainy season, the route had to be adjusted to the weather, which was handled perfectly. We simply spent a little more time on Pig Island than we did snorkeling. This gave us extra time to explore the beautiful island, in addition to feeding the pigs! We also went swimming... Afterwards, we went snorkeling and saw some cool fish. Because the weather suddenly turned bad, the return trip was quite an adventure! Luckily, nothing serious happened except that we got wet. You could tell the guides were used to the weather 😂 Overall, a truly amazing experience! I would definitely do it again!
