About this site
Koh Larn is an island off the coast of Pattaya in Chonburi Province, a short boat ride from the mainland piers at Bang Lamung District. The waters around the island are part of the Gulf of Thailand's inshore diving and snorkeling area, popular with day-trip operators out of Pattaya. The reef diving here reaches a maximum depth of around 24 metres and is rated as a beginner site, making it a common choice for those starting out or looking for an easy dive close to shore.
