Read what other Viator.com travelers think about the Koh Nang Yuan and Koh Tao Snorkeling Tour from Koh Samui. What they loved, what they liked and what they think could be improved, it's all here to help you make the most of your next trip.
The trip out was very rough, which meant fun for some people and using the bag for others. We went to some nice snorkeling places, and the view from the beach restaurant was great.
I thoroughly recommend visiting Koh Tao but do not use this tour company. On our boat only two out of three engines worked, and we were over taken by many other speed boats as we were so slow, spending about 4 hours in a very overcrowded speedboat. Also, don't expect flippers for snorkelling :(
