The Similan Islands feel far removed from the busy beaches and marinas of Phuket. Located off the coast of Phang Nga, this national park is known for rounded granite boulders, pale sand and remarkably clear water. It is a place where the shape of the coastline matters as much as the sea itself.
The name “Similan” comes from a Malay word meaning “nine.” The islands are often described as a group, but each has its own outline, beaches and relationship with the water. Some are defined by enormous smooth boulders; others have smaller coves and forested slopes. Seen from a boat, the islands appear and disappear against the open Andaman horizon.
Above and below the surface
The scenery continues underwater. Clear conditions can reveal reef formations and fish close to the surface, while deeper water offers a different experience for qualified divers. Visibility and marine life vary with season and conditions, so no two days are exactly alike.
For snorkellers, the appeal is the chance to pause above a living reef and watch the light move across the water. It is worth taking that time slowly. Coral is delicate, and touching or standing on it can cause damage. A careful visitor leaves the water as they found it.
A trip that needs planning
The Similans are not a quick stop on a standard island-hopping day from Phuket. Most visitors arrange a separate excursion from the Phang Nga coast, commonly departing from Thap Lamu. The Tourism Authority of Thailand describes the crossing by speedboat as taking around an hour and a half, with visits planned as day trips. Overnight arrangements and park access should always be checked in advance.
The national park closes seasonally, and opening dates, permitted activities and visitor rules can change. Check current official information before booking rather than relying on an old itinerary or a previous season’s schedule.
Is it the right destination for you?
A Similan trip suits travellers who are happy to spend time getting there in return for a more remote natural setting. It is especially appealing to people who enjoy swimming, snorkelling, diving and taking in the landscape without needing a long list of stops.
For guests staying in Phuket, it is useful to think of the Similans as a separate adventure rather than an extension of a nearby yacht charter. The journey requires its own transport and planning. The reward is a quieter, more open side of the Andaman - and the chance to experience the islands at the pace of the sea.
