Surin Koh is beside the Similans one of the best dive sites in Thailand. The archipelago is a national park since 1981, there are no hotels or resorts, only a small lodge and a restaurant. Koh Surin Nua and Koh Surin Tai are about 70 km west of the mainland. They are covered with dense jungle vegetation, numerous coves and glorious white sandy beaches, which attract more and more day-trippers to the islands for snorkeling, swimming and of course diving. Some hundred sea gypsies, the Chaoleh, are living on the island, catching fish and provide longtail boat trips around the islands and to the many bays. After the tsunami of 2004, they moved there houses to the saver place on the northeast coast, just south of Ao Bon. Almost all places and beaches can be reached also by walking through the island on sandy trails. On weekends and holidays especially Thais come to Surin for snorkeling.

It is wise to take some food while the only local restaurant is not very good. A small kiosk sell some articles for the daily life. Only some people are able to speak and understand english. Koh Surin is a diving target for diving boats from Khao Lak or Phuket, so in high season sometimes quite many boats and divers can be seen at the various diving spots. The average sea depth is between 10 and 20m. The most beautiful diving spots are:

  • Koh Ree (up to 23m, barracuda, tuna, mackerel, various turtle)
  • Hin Rap (up to 24m, whale sharks, manta rays, corals, turtles)
  • Ao Ngam May (up to 16m, shrimp, turtles, rays)
