We absolutely looooved this tour! Everyone on board was so friendly and if you were active and interested like we were, they’re going to start making jokes with you. These guys are snorkeling experts and are insane at holding their breath! They make pictures of you and while you’re already back up, they’re still down there taking a full 1 minute shot of the turtles😅. We saw so many fish and 3 turtles!! A lot of pictures were made which was so fun. Since you are with a less famous tour (than for example Diamond tour you see everywhere) you are with a smaller boat so it feels a little more secluded. We also met so many nice people on board from all over the world. Definitely recommend!

Snorkeling Tour to all the famous spots. Group size was good and compared to other companies a rather small size. Still in the water it could get crowded with everyone being in the way of each other. Also we would have liked more guidance and explanation of the wildlife

Although the excursion was well organized and staff was very helpful and friendly, nevertheless our expectations were not exceeded, hardly any fish, only a baby shark and a single turtle

This is an excellent full-day snorkeling tour of Koh Tao, and comes at a great price. For us it was basically a 9am-5pm day, with some extra time for (free, included) transport on either side of that. The tour boat takes a full lap around Koh Tao and stops at 5 snorkeling locations, with the first stop including a beach, small hike, and restaurant/bar. The views are incredible. The included underwater photos are a great perk. We saw turtles, sharks, and lots of fish and coral. You're on a ~30-40 person boat (which was full at peak season, but the tour guide said they operate closer to half-capacity in the low season). The tour team is communicative and organized. A simple lunch is included on the boat. The only thing I'd note for improvement is that some of the snorkeling masks leak a lot, which makes them a bit challenging to use. Newer or higher-quality masks would be great.
