Pattaya has a number of islands in its vicinity of which “Koh Lan” is the largest. 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.
