In retrospect this tour , due to the very strong winds, was not our best choice. Though credit to the Staff and boat driver ( along with sea sickness tablets) for getting us back safely to the jetty, after a very long day ! Floating jetties are an absolute nightmare and extremely dangerous with crashing waves, and often required two staff members to help guests to land. Overall, quite disappointed.

Too many people in the boats, the windows are too high we don't even see the scenery, when we get up to look we are asked to sit. the dive is nice about 20 minutes but that's all! really not great as a tour operator. you have to better see on the spot the fishermen on site who charge 4 times cheaper rates and who take you to heavenly corners.

The landscapes are incredibly beautiful, with tropical beaches and golden sand. The waters of the beaches, perhaps due to the wave activity on the day of the trip, were murky. The lunch we had was tasty, with a variety of options, including choices for vegetarians. However, I would like to focus on two issues: 1. Due to the wave activity and strong winds (approximately four to five Beaufort), the journey was quite challenging. Moreover, there was no indication, except right before boarding at the dock, that this particular trip could be dangerous for pregnant individuals or those with back problems due to the intense shaking of the boat. At times, I felt concerned for my safety. & 2. The second issue is the limited time we had available to explore and enjoy these beautiful places, as there were numerous stops at several islands.

To many people and the boat it bumpy the food was ok for lunch the staff and work they best to help but when we book it say 30 when we get there it was 43 people so it not as advertised so try to buy this trip from local in stead of Viator because you pay more full price and the tour still lied to you it 25 to 30 but they try to make more money for high season

the trip was amazing, well organized, pick up on time, the morning gathering of all groups was a bit of a surprise but they handled it very well, toast and jam for breakfast was a bit sad but we had our own snacks, the tour guides were awesome, especially Ken, attentive, knowledgable, funny and really looking after each participant with care, amazing guy! All stops included as planned, snorkeling was in the open waters from the boat so not for the heart fainted, kayaking amazing, the lunch was decent and tasty, highlight was the hike to the viewing point of the Ang Thong marine park, super hard but we did it and oh was it worth it!!!!!! Couldnt do it without the cheer from Ken :) there were couples, families with children as little as 4, as well as a few "elderly" couples, really amazing! For Ang Thong pack extra clothes in case u het wet, wear ur swimwear already since snorkling is first, loads of sunscreen as u r out in the open all day long, proper shoes for the hike as its rocky and very steep! and flip flops or water shoes for the boat parts! THANK YOU FOR AN AMAZING DAY❤️

This is one of the best day trips I have done, anywhere. A nice speedboat, beautiful scenery and a good lunch. Overall, the snorkelling was good, the kayaking excellent and the beaches visited were stunning. I skipped the hike. Special mention to our tour leader Tony and the boat crew. Kept you well informed on the areas we visited, spoke good, clear English, was very funny and most importantly, safety was paramount. Plenty of water and snacks given out when travelling between venues. Probably my favourite day in Thailand this trip. Serious value for money. Thank you to all involved.

A very enjoyable trip, not to be missed whilst staying in Koh Samui. Swimming, snorkeling, kayaking, hiking or just enjoying the beach and stunning views, this trip has everything. AK and his crew looked after everyone exceptionally well. Thank you so much
