It was a great experience. Neat and Comfortable boat. Courteous guide and staff. Timely pickup in comfortable van. However, on return, the van was changed which was not so comfortable. There were other guest as well who were dropped on way back. We were 5 pax ans staying in Sheraton. Driver dropped us at exit and refused to take the van to the porch where as all other guest were dropped at the Porch. This small incident created a dent in happy memories.

I absolutely loved this trip. It was comfortable, couple-friendly, and the people were incredibly kind and fun, especially Win. I don't know how to swim, and Win was kind enough to help me snorkel by having me wear a life jacket and guiding me through the ocean using another jacket which I held onto from side and him from the other. I was honestly quite scared to enter the water, even with the life jacket on, but he was patient, non-judgmental, and extremely kind throughout. He made me feel safe and comfortable, which allowed me to enjoy an experience I otherwise would have missed. Thank you, Win, for your warmth, encouragement, and kindness. You were a big part of what made this trip so memorable for me.

We had an amazing experience on our tour! The boat was spotless, the staff was incredible, and the views were unforgettable. We were constantly handed food and drinks throughout the day and everything was so yummy. The tour guides were very attentive and helpful, not to mention they had a great sense of humor. I would highly recommend a trip or with them while in Koh Samui, it's a do not miss!

The trip was canceled due to weather. They still picked us up and brought us to tour before canceling. They should have canceled it before getting us. It wasted our time and affected our day.

Had such a great day with Happy Samui Boat Tour 🌴☀️ The group size was perfect, big enough to be social but still small enough to feel relaxed and personalised. The sights were absolutely beautiful, the stops were well chosen, and the whole day ran really smoothly. A huge shoutout to Win and the rest of the team, who were amazing guides throughout the tour. Friendly, organised, and made the experience really enjoyable from start to finish. I’d definitely recommend paying a little extra for one of the smaller group tours. It genuinely makes such a difference to the overall experience and gives the day a much more personal feel. Highly recommend if you’re visiting Koh Samui!

It’s a great day but don’t be hungover and take a crap before you get on the boat. Superman was our lead guide. Awesome dude as well as his team. The lunch we had was so good.
