We saw loads of colourful fish, coral, black tip reef sharks and turtles. The tour guides were great and took loads of underwater photos of everyone. Nice lunch too.

Such a fun day!!! Koh Tao is a stunning island to visit by boat with lots of gorgeous beaches, inlets and snorkeling bays. The boat was basic but also very accomodating and comfortable, plenty of space and loads of activities!!! The climbing wall, waterslide and jump were all in constant use and loads of fun. Staff were amazing, incredibly friendly and helpful and they even gave everyone on board free pics of their day in and out of the water. Lunch again was basic but fine. We were a family of 6 and everyone loved it!!

This was a really well run day out! The crew were excellent and the boat had a great vibe. Food was top notch. There was some algae around for some of the snorkel stops which was juts bad luck, but I wouldn't let this put you off. Jumping off off the boat was a highlight!
