Khao Sok

 If you need a break from the beach head up to the Khao Sok, which has the largest area of rainforest in southern Thailand. Canoe safaris are a good way to explore the area, as is an elephant trek through the forest. If you have any time left then hire a boat at the Cheow Larn Lake and spend the night in one of the traditional houses on the lakeside.

Krabi

 This isn't really a place most travellers choose to stay, it is more of a transit hub, the place where you cath ferries to places like Phi Phi island or Koh Lanta. Just out of the city is the Kho Phanom Bencha national park. Worth a visit for its impressive waterfalls and creepy cave landscape.

Phi Phi island

 Although the 2004 Christmas tsunami changed the face of this island, since the tragedy lots of re-building has taken place. Ferries and long-tail boats run services to this paradise where gorgeous white beaches meet tropical jungle.

Coral island and Racha island

 For all snorkelers and divers out there, strap on your fins and head to the south of Phuket. These islands are perfect for day or overnight stays. No cars, only pure white sands and coral reefs, teeming with tropical fish.
