Koh Tao, or Turtle Island, is the scuba diving certification capital of Southeast Asia. Since the cost of getting a scuba diving certification here is 1/2 or even 1/3 the cost in Europe, many backpackers opt to pick up their certification here. I decided to do the same!
To get to here, from Bangkok I first took an overnight sleeper train (that arrived 3 hours behind schedule) to Chumphon, then a ferry from Chumphon to Koh Tao.
