Boat-access coral reef near Pattaya.
Koh Khram Noi is a boat-reached coral reef off the Pattaya and Samaesan side of the Gulf of Thailand, with hard coral on the east, sea fans at the north tip, and strong reef life across the structure. It suits relaxed reef dives when the island is open, with turtles and schooling fish around the coral and occasional access checks because the area sits in a managed naval zone.
