Koh Hong (Room Island) is part of a group of islands one hour north of Krabi. Koh Hong has only one beach - Pelay Beach - but it is recognized for being extremely beautiful, boasting fine white sand, coral and lots of varieties of tropical fish. Pelay Beach is framed by limestone rock formations which give it an enclosed feel. Coupled with the fact that there are seldom many people there, Koh Hong very much offers a ‘desert island’ experience. Its name comes from an eroded group of caves in the middle of the island which harbours a large lake with a small passage to the sea. When the tide is high long tail boats are able to enter the ‘room’ and visitors can swim in around in crystal clear water with a depth of around one metre. Koh Hong is another collection point for the nests that provide the ingredients for bird’s nest soup.
