Such a great day. Mr Yai, the star of the show, and his excellent crew were efficient and professional. We felt safe at all times! The itinerary was just lovely with just the right amount of variety. Basically everything was supplied. Lunch was yummy. Hotel pickup made it all super easy. Don’t miss this tour!

The 4 guys on the boat gave terrific service. There were fresh fruit platters, cookies, cakes, and plenty of sodas and waters on the boat. The snorkeling was fantastic. Kayaking through sea caves was a lot of fun. We stopped for a great hot lunch on a small island with fish, chicken and veggie entrees. The crew always aimed to please.

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.
