The variety of corals also supports a rich ecosystem, making every dive a unique experience.

Historical and Cultural Background

The Similan Islands, including Stonehenge, were declared a national park in 1982 to protect their unique marine and terrestrial ecosystems. The name "Similan" comes from the Malay word for nine, reflecting the original nine islands that make up the archipelago. The area has long been revered by local communities for its natural beauty and biodiversity, and it continues to be a significant site for conservation efforts.
