Reviews: One-day tour to Angthong Marine National Park

Guest User2026-01-16

A fantastic excursion! The snorkeling reef is vibrant and vibrant, with plenty of fish. The islands are beautiful. The kayaks aren't exactly the freshest, but they do their job. We were fed heartily, and the views from the observation decks are simply stunning! A fantastic excursion!

A great excursion tour! They took us there, fed us, and entertained us. The landscape is like a Windows screensaver. A great way to spice up your vacation and try several activities in one go. Just don't take this tour if you're flying out the same day, like I did. I arrived at the hotel around 7:00 PM, when the description said 5:00 PM.

Reviews: From Koh Samui: Day Tour Ang Thong with Kayak, Snorkel & Lunch

Guest User2026-01-01

Since I was already in Koh Samui, I decided to visit one of the islands and signed up for this tour. My expectations weren't high, but I enjoyed the trekking. The snorkeling in the bay at the end was surprisingly good, with schools of fish clearly visible. However, the current was strong, so I worried I might not make it back to the cave in time, so I snorkeled around the boat. The trekking section was quite steep and involved unsteady stone steps, so it's best to wear sneakers if possible. However, I didn't see any information about this, so I ended up wearing flip-flops. I bought water shoes on the boat, but they were too big and didn't fit. They were a bit cheap for 300 baht, so I ended up having to use them for disposables, which left me feeling like I wasted money. However, the Burmese guide was very entertaining, and overall, it was a very enjoyable tour.

Awesome experience The guy were very helpful and they took really good care of us. To be honest, I do not understand why people have some critics about this expedition. It is absolutely amazing.
