Koh Yao Noi (“long, little island” in Thai, though it is neither particularly long nor little), is located in Phang Nga Bay between Krabi and Phuket, and is the most up-and-coming destination in southern Thailand.
Ideally situated to offer the visitor a front-row view of Phang Nga Bay’s incomparably beautiful karst cathedrals, Koh Yao Noi is also a well-placed base from which to explore the bay, as the visitor can reach the world-class tropical kayaking destinations earlier in the day, before the crowds from Phuket envelope them.
In 2002, Koh Yao Noi gained worldwide attention after receiving the World Legacy Award for Destination Stewardship from National Geographic Traveler magazine.
