4.00It was a great time! I didn’t realize how long the boat ride would be, so definitely check the weather beforehand if you’re even a little prone to seasickness. Our ride back was very choppy, a few people got sick.
If you are looking for good snorkeling, this is not the excursion for you.

1.00The speedboat was full of tourists. As you are sitting on the boat, you cannot see the view. The boat smells like diesel fuel. The crew were nice and helpful, and generous with the water. However, at the beginning of the trip, they scare you into buying water shoes so that you will not get injured by the sea urchins. While we did not fall for that scam, most people did. Not a single sea urchin was seen by anyone the entire day. Also, they take your shoes and do not give them back until the end of the trip, so you are forced to either walk barefoot, or wear their $10 shoes. After riding for 1 hour 45 min., we arrived at the first snorkel spot - near the rocks. Poor visibility and very few fish. The second spot was a tad bit better and I did see a turtle and fish, but still poor visibility. Lunch was buffet and terrible food. Lastly, we were taken to the island, which was beautiful, but overrun with tourists. If you are looking for good snorkeling in Thailand, this is NOT your trip. Try the Surin Islands.
Fantastic day

5.00We absolutely enjoyed the trip and had an amazing time snorkelling in Koh Tao and hiking around the beautiful Koh Nang Yuan. With the help of a tour guide, we were lucky enough to spot a turtle and capture some great photos and videos. The tour guides spoke good English and were very friendly and helpful throughout the experience.
Decent not great

3.00The people who run this are very nice and friendly but the experience is over-crowded and only okay. The boat is packed. The first snorkel spot is filled with sea lice that nip at your body. The second spot is nice water but not many fish. The third stop is a beautiful island but it is so crowded you can barely move and cant find a spot to relax. Lunch was not good. This trip would be great if they decreased the number of people on the boat by 50% and the number of boats going to the private island by 80%.
Good tour

3.00The tour was great, each location was beautiful, however the 3hr total ride there and back was rough. I think it is better to spend a night or two in Kao Tao instead. Everyone thought the island was so beautiful and we just didn’t get much time in each spot to enjoy it. Food was ok, a bit cold, everything was very efficient tho.!
Outstanding!
