Phuket is the biggest island in Thailand, located in the Andaman Sea off southern Thailand. The island is mostly mountainous with a mountain range in the west of the island from the north to the south. The mountains of Phuket form the southern end of the Phuket mountain range, which ranges for 440 km from the Kra Isthmus. The highest elevation of the island is Mai Thao Sip Song (Twelve Canes), at 529 m above sea level.

In the mountainous north of the island is the Khao Phra Thaeo Non-hunting Area, protecting more than 20 km² of rainforest. The three highest peaks of this reserve are the Khao Prathiu (384 m), Khao Bang Pae (388 m) and Khao Phara (422 m). The Sirinat National Park on the northwestern coast was established in 1981 and protects an area of 90 km² (68 km² marine area), including the Nai Yang beach where sea turtles lay their eggs.
One of the most popular tourist spot areas on Phuket is Patong Beach on the central western coast, perhaps owing to the easy access to its wide and long beach. Most of Phuket’s nightlife and its cheap shopping is located in Patong, and the area has become increasingly developed. Patong means “the forest filled with banana leaves” in Thai.- Best Tourist spot in Asia
