Long Island is a group of islands between Phuket and Krabi. There are two main islands, Koh Yao Noi (Small Long Island) and Koh Yao Yai, (Big Long Island). Koh Yao Noi remains a beautiful island where most people still believe that the island should be preserved from human degradation. It is often described as one of the last islands in the region to become over developed.

In 2002, Koh Yao Noi gained worldwide attention after receiving the World Legacy Award for Destination Stewardship from Conservation International and National Geographic Traveler magazine for the eco-friendly home-stay programs offered by its local residents. Koh Yao Yai is also a natural beauty, being one of the less-developed of the two islands. Koh Yao Yai is significantly larger than Koh Yao Noi.

Other activities available on the island include agricultural demonstrations (rubber and fishing), kayaking, hiking, snorkelling and swimming.
