Thailand Diving

Famous for its tropical rainforest, rich culture and beautiful beaches Thailand diving is also a popular attraction that draws thousands of tourists each year. Thailand's almost 2000km of coastline offers divers a bevy of sights, from fringing reefs and seamounts to caverns, drop-offs, tunnels, walls, wrecks and pinnacles, not to mention the colourful and exotic marine life. There are a great range of operators who offer everything from equipment hire to day trips and even liveaboard overnight adventures.

With water temperatures averaging 28-30° C year round, mild currents, visibility of approximately 30m and varying depths up to 36m Thailand diving is suitable for most skill levels and is good year round. However, the Gulf of Thailand is at its best from May to September while the Andaman Sea is best from October to April. Below is a list of some of the best Thailand diving sites.
