Since 1982 the Similan islands are a national marine park. No people live on the islands, only two restaurants - on Koh Similan and Koh Miang - and some simple huts and tents provide food and accomodation für guests. Most people come for snorkeling daytrips or by diving boats from Phuket or other destinations.

North of the main Similan islands group lays Koh Tachai, a beautiful unspoiled jungle island with white sandy coral beaches. Day trips for snorkeling and enjoying the beaches are offered by several speedboat companies like Koh Tachai has no infrastructure and no possibility to stay overnight.

Getting there

By speed boats from Phuket or Khao Lak, needing about two hours to reach the Similans. The boats leave early in the morning and stop at various places for snorkeling and lunch time. The boats return in late afternoon. In windy weather conditions the passage on the wave jumping boats can be very tough and tiring. In good weather conditions the islands are a must see.


On Koh Similan and Koh Miang there are tents for rent and a few simple huts for guests, who want to stay some days. Most guests just come for a daytrip visit from Phuket or Khao Lak.

During rainy season from mid May till mid November the islands are closed.
