Ko Samui is Thailand's third largest island and much of it is still covered by coconut plantations, verdant clad jungle and rugged mountains of granite that roll down into the warm clear waters of its azure sea. The island itself lays 35kms to the east of Surat Thani, its provincial mainland capital and measures 21km long by 25km wide. Nowadays it is a preferred base for divers who are looking for an up-market western infrastructure in the Gulf of Thailand.

Many tour activities are available apart from diving if you are travelling with non-divers or children too young to try diving. Sailing is popular with so many groups of small tropical islands to explore nearby. The Kiaora catamaran departing daily from the BBC Restaurant near Big Buddha offers a relaxing day sailing on a spacious luxury boat. Jet Ski hire and other more adrenaline packed activities are also readily available.

All in all the extensive tour and adventure activities offered make Koh Samui a comfortable upcoming high-end resort destination and all of the dive sites that are dived from Ko Tao are accessible from Samui though the diving journeys are longer.
