Class tour

Everything went smoothly. Small breakfast and lunch. Had good weather and the ride was very quiet. The climb was very exhausting. Please think carefully if you're going up there. The day after is painful πŸ˜‚

Dreamlike

Great trip. We paddled by canoe to the first island, which is highly recommended. Could then choose whether we wanted to swim, snorkel or hike. We opted for the steep ascent and descent via stairs to lagoon and back. On the second approached island we decided to go for a strenuous steep hike, partly for climbing, to hell. Was a great day with breathtaking scenery.

Nice day trip from Koh Samui

The tour was well organized, the hotel pick-up very convenient. We stopped on two islands and I liked the freedom we had on each island, but it would be nice to stay longer on Koh Wua Talap, to allow people to visit both the cave and the view point. The staff were kind and helpful as the floating piers proved to be very challenging in the rough sea. Motion sickness pills were provided on board. Unfortunately I relied on the breakfast served on the boat, based on the description, and that was a mistake. It was only a banana and a very sweet baking powder tasting muffin. Have a proper breakfast before boarding. Otherwise, highly recommended.

Great experience with muscle soreness!!

The tour is recommended! The first ascent (to the lagoon) is no problem. The second ascent to the view point is challenging! We had two days of the worst muscle soreness in our legs afterwards πŸ™†πŸ˜… But the view is outstanding from up there! The food on the boat tasted good.
