This was a great experience from start to finish. Our guide Yai was brilliant, very comical, accommodating and spoke very good English. The crew on board were also brilliant. We went to the view point to over look the beautiful lagoon and then headed back to the boat for our next stop of snorkelling. The equipment was given to us on board, Mask Snorkel and fins and were in good condition. The water was a little mirky but that was to be expected due to recent storm. We then headed for our next stop which was Kayaking. This was great fun and a little workout at the same time. We then went for a lovely lunch, which catered very well for us Veggies! We then stopped at the beach for our final stop which was pretty much Paradise! There were very few people on the beach, which made the hour stop for a chill and gentle swim even more serene. Well organised, safe and enjoyable trip! We would book again.

Great trip with a small group. We left early, which made us come before all the other tourists. OK snorkeling - not quite wild with corals, but fine fish. Nice relaxing visit to a beach. Nice Thai buffet for lunch.

Really beautiful day with multiple stops - for kayaking, high view point (worth it even if itâs a tourist trap), snorkeling, lunch restaurant, and a private beach. Professional crew and everything was well organised from pickup to drop off. The main guide of the crew did all of the taking, their English is ok - donât expect an audio tour type experience though, just enjoy the views and being out on sea :) youâll also notice the contrast of looking one way to see crystal clear water, and behind you lots of rubbish in the bush or ocean. Either way I would really recommend this trip, my highlight of my stay in Samui!
