Southern Thailand plays host to some of the Kingdom's biggest tourist drawcards. From diving off Ko Tao, to climbing in Krabi, kayaking of Phuket or just laying in a hammock pretty much anywhere, Southern Thailand really does have something to offer so many different interest.
The southern region of Thailand is climatically split in two -- the south east and the south west. Each is affected by a different monsoon through the year meaning that regardless of when you're in Thailand, you'll be able to get a slice of good weather somewhere.
The islands of Phuket, Ko Samui, Ko Pha Ngan and Ko Tao are probably the best known of Southern Thailand's islands, though there's over a dozen others to choose from -- all with accommodation and at least semi-regular ferry connections. Don't make the mistake of thinking this quartet of islands is all the South has to offer.
