The numerous islands along the coast makes Surat Thani a perfect hideaway for vacationers from around the world. The ideal destination for many is the Penang-sized Ko Samui, Thailand's third largest island, and its neighbour Ko Pha-ngan a celebrated island that hosts the biggest beach full moon party. North of Ko Pha-ngan is Ko Tao, renowned for its excellent coral reefs. To top it all is the dazzling 250-square-kilometer Ang Thong Marine National Park, where a stunning archipelago awaits to greet visitors with their charming palm-fringed beaches, crystal clear water and colorful coral reefs. The best time to enjoy one of these islands to the fullest is from April November.
