It is the closest island to the Cambodian border in Trat province, approximately 330 km southeast from Bangkok and doesn't belong to the Mu Ko Chang National Park anymore. Koh Kood (often also written Koh Kot or Koh Kut) extends over approximately 23 kilometers in length, almost 9 kilometers in width and has a size of about 129 square kilometers. During high-season there are 2 daily Island-Hopper boats (8 am and 12 am - Island-Hopper) from Baan Bang Bao in the south of Ko Chang to Koh Mak (tickets available in many travel agencies on Koh Chang). From the pier at the west coast of Koh Mak take one of the taxis that are waiting there and go to the pier at the other side of Koh Mak (Ao Nid Pier). From there a speedboat leaves at about 11.45 am to Koh Kood, the journey takes about 30 minutes. The boats to Koh Mak only leave if there are enough passengers, so it may happen that some trips are cancelled! In low-season between May and November there are no regular boat connections. In addition there are also boats between Laem Ngop and Koh Kood, but because they only leave irregularly, better ask in the travel agencies or at the piers.
