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: From Koh Samui: Day Tour Ang Thong with Kayak, Snorkel & Lunch
Guest User2026-08-20
🌴 Excellent island tour – highly recommended! I really enjoyed the organization of the tour! From the very beginning, we were fed sandwiches with jam and had unlimited drinks. Water was constantly provided throughout the trip – there was enough for everyone. The lunch was also great: watermelon and Thai dishes. We had plenty of time at each location: we snorkeled peacefully with the fish and admired the corals, and on the island, we even managed to climb to the observation deck. I'd especially like to highlight the attentiveness of the guides: during the ascent and descent, they stood along the route and offered water. The guide constantly offered to take photos, and my parents even took a romantic video. ❤️ I rate the work of the guide and the entire team 100/10! Everything was organized comfortably, attentively, and with care for the tourists. Take the tour – you definitely won't regret it! 🌴🐠

Reviews: Koh Samui: Private Longtail Boat to Pig Island with Snorkel
Guest User2026-07-27
We have nothing negative to report, even though the island is relatively crowded. The children were delighted and had a great time. Departure from Koh Samui, pick-up from Koh Madsum, and the snorkeling trip went perfectly and as agreed. Our "captain" was very friendly, reliable, and punctual. We would definitely book through this company again 👍🏼

Reviews: From Koh Samui: Koh Tao & Nang Yuan Tour with Snorkel and Lunch
Guest User2026-09-12
We originally planned to have Koh Tao trip but it was cancelled because of the weather and we get opportunity to join Ang Thong trip at the check-in place without additional payments. It was overcast so the islands and water view were not so magic bright but good enough; post windy weather reduced visibility in the water also, but we still were able to see some corals and fish. For those who wants to see “OLED” picture underwater - look for the sunny calm wind days. Otherwise the trip itself was organized well: responsive and helpful friendly crew, assistance of taking photos, fast speed boat, constant water supply, good lunch. Beautiful view points, snorkeling, kayaking around island. Take good sandals instead of slippers to climb better to the island’s top and water shoes to swim safely. Was a very nice day.
