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 :(
I have been several times in those kind of snorkelling tours in Phuket and without any doubt I can tell that this Koh Samui tour was the 'biggest torture' I have ever seen. First of all there were more than 25 people in the speed boat.We were sitting very uncomfortable due to the crowd also all got wet nonstop because of the waves during 3 hours of travel in total in a very rough sea. Seem like refugees
Net snorkelling time was around only 2 hours.
The only good thing that I have to mention is the transfer shuttle and its kind driver between hotel and the tour point.Overall this experience was a huge disappointment for me and as a result that was the first and the last time of my viator booking.
