The small island of Koh Kradan is reputed to have the most beautiful beaches in the province. Its pretty turquoise waters and white sand provide a postcard backdrop. Koh Kradan, unlike koh Mook, has no village or local life, there are only small resorts in a row and a minimart. The rest of the island is part of Hat Chao Mai National Park. Notice that if you go to the top north or to the west beach, you'll see a lot of rubbish. This is really a shame, but that happens a lot in Thailand sadly.
