Diving in Koh Samui
You can expect excellent, well-organised diving on Koh Samui. As one of the most developed islands in the region it has some nice shore dives, but the best dives are from a boat, taking one out for the day and enjoying two dives. The best diving is from March to September and Koh Samui offers access to a whole host of different sites where you can spot everything from whale sharks and turtles to schooling fish. The great thing about basing yourself here is the mix of beaches, hotels and restaurants that can be enjoyed too.
