We have traveled Thailand often and we get to some far away places. Never felt threatened during all our travels.

Koh Tao is the destination for your snorkeling and diving. Absolutely magnificent. You can do an around the island snorkeling trip first and if you like it do a dive course there.

Kph Phangan is a beautiful island and there is no need to get caught up in the party scene if you don't want to. The FMPs have got out of hand lately, with drugs, theft and some violence from both the local and party goers. There was some talk of the parties being stopped all together.
