About This Anchorage
Koh Nang Yuan is a unique cluster of three small islands connected by two stunning white sand bars, creating one of Thailand's most photographed landscapes. Located 1nm northwest of Koh Tao, the anchorage is in the channels between the three islands in clear turquoise water over sand and coral. Day visitors pay a fee to visit the island resort. Overnight anchoring is exceptional — the sunset views between the sand bars are extraordinary.
