Spend a leisurely day from Phuket aboard a speed catamaran to the Similan Islands. Snorkel iconic sites like Sailing Rock and Christmas Point, enjoy beachfront lunch at Princess Bay, and return with close encounters of turtles and vivid reef life.
More ways to explore the area's outdoor wonders
You step onto the brushed-deck catamaran just as the island silhouettes sharpen against a bright Andaman sky. The boat hums, and the sea dares you forward — a long blue road toward bouldered granite and powder-white sand. By late morning the Similan Islands unfold: Sailing Rock’s stacked domes, sheltered bays that glint like coins, and coral gardens threaded beneath the surface.

Mu Ko Similan became a national park in 1982 to protect its coral reefs and island ecosystems; granite formations are remnants of ancient continental crust.
Conservation
The park enforces seasonal closures, visitor limits and reef-friendly guidelines; use only reef-safe sunscreen and avoid touching coral to minimize impact.

Bring reef-safe sunscreen
Apply reef-safe SPF before boarding and carry a small bottle to reapply after snorkeling to protect coral and skin.
Sea-sickness prep
If you get seasick, take medication an hour before departure and sit mid-boat where motion is least noticeable.
Footwear for shore
Wear sturdy water shoes for short rocky walks and beach entry rather than flip-flops, which can slip on wet granite.
Secure valuables
Use a waterproof dry bag for cameras and phones; the boat provides storage but waves and sprays are common.
Reef-safe sunscreen
Protects your skin and the coral reefs during extended sun exposure on deck and at the surface.
