Koh Larn, also called Coral Island, is the island 7 km off Pattaya with the clearest water on this coast and several beaches. The speedboat makes the crossing in minutes and adds Koh Sak, a smaller and calmer island for snorkeling. Snorkeling gear, a paddle board and bottled water are included; parasailing, the sea walk and jet skis are optional extras you pay on the spot.
