I came to dive in Koh Tao.
There are litterally dozens of dive shops in Koh Tao, many more than figuring on the web. I chose Crystal after looking over a number and it was the right choice.
Being an experienced diver I wanted to be taken to as many different sites as possible and this is what I got.
Crystal run 3 big boats that leave from the pier, so divers do not have to be transfered from the beach. You just walk on. For fun-divers, Crystal provides experienced Dive Masters who know the sites. Each DM takes a small group of about 4 divers. Also, security is paramount. The boat master does a roll call after embarcation and after each dive. One can dive up to 4 times per day and the die-hards can also do a night dive on certain days.
All in all it was a most pleasant and rewarding experience.
I lodged in the adjacent Regal Resort, a room with a view on the ocean, facing west, with incredible sunsets. The room was very large and kept very clean. Complimentary bottled water was provided daily. The swimming pool was appealing but I used it only once, the sea being a stone throw away.
A lovely 10 day holiday in this island.More
