The island is somewhat an extension of the mainland activities, featuring water sports such as diving snorkeling, windsurfing, waterskiing and para-sending. A key attraction is boats sailing around the island for sightseeing purposes. Some of the boats have glass bottoms enabling passengers to see coral and marine life at the bottom of the sea.
The island has a number of beaches, the main beach hosting a number of excellent seafood restaurants selling dishes made from freshly caught seafood. The area also features deep sea fishing boats around Koh Lan’s neighbours, Koh Krok and Koh Sak.
