Mu Ko Similan and the granite forms of Phang Nga
Published on 08/29/2026 at 14:47 | Editorial responsibility: Rafael Müller, Editor-in-Chief AD HOC NEWS
Mu Ko Similan is an island group in Phang Nga, off Thailand’s west coast, known for its granite forms and clear edges between rock, sand and sea. The archipelago became a national park in 1982, and that status remains central to its identity. The name Mu Ko Similan points to a landscape rather than a town, and the islands are the focus.
Granite islands in the Andaman Sea
The Similan Islands sit in the Andaman Sea, forming a chain of islands rather than a single mass. Their granite is visible in smooth slabs, rounded boulders and darker seams across the shoreline.
The park is associated with the nine Similan Islands, and the wider protected area includes Mu Ko Similan National Park. The park was established in 1982, placing the islands within a formally protected seascape.
A protected seascape with a named identity
The islands have long been linked with Thailand’s Andaman coast and the province of Phang Nga. Their setting combines open water, small coves and headlands, with the granite dominating the visual character of the coast.
The park’s official record identifies Mu Ko Similan National Park in Phang-Nga Province, while the broader archipelago is described as a protected marine landscape. The islands also appear on Thailand’s Andaman Sea Nature Reserves tentative World Heritage list, which underlines their formal status.
Rock, water and reef on the same shore
What gives Mu Ko Similan its character is the close meeting of granite, beach and shallow water. The coastline changes quickly from stone outcrops to pale sand and then to the sea.
The islands are part of a broader reef environment in which the shoreline and the underwater landscape belong together. That pairing of hard rock and marine habitat is the main visual theme of the place.
Visiting Mu Ko Similan: what travellers from Western Europe should know
- The islands lie off Phang Nga in the Andaman Sea. Access is by boat from the mainland, with the park office and visitor facilities onshore near Thap Lamu.
- The terrain is rocky in places, with granite slabs, boulders and short shore approaches. Walking across parts of the islands means moving over uneven ground.
- The archipelago is a marine park, so the sea is part of the visit as much as the land. Snorkelling and boat travel are closely tied to the setting.
- The official language is Thai and the currency is the Thai baht.
