Designated in

1982

Established in 1982, the Similan Islands archipelago has been repeatedly ranked among the ten best diving destinations in the world by international specialist publications, thanks to the extraordinary visibility of its water and the diversity of its coral reefs. Since 2018 the Thai authorities have closed the park for six months each year, from May to October, coinciding with the monsoon, both on safety grounds and to allow the marine ecosystem to recover naturally in the face of growing tourist pressure.
