The catamaran cleaves a wide arc of turquoise, spray bright against the sun, and Khao Lak recedes to a thin green line. By midmorning you’re anchored off an icon—Sailing Rock on Island No.8—where granite boulders rise like sculpted steps above white sand and the current starts to dare you into the water.

The catamaran cleaves a wide arc of turquoise, spray bright against the sun, and Khao Lak recedes to a thin green line. By midmorning you’re anchored off an icon—Sailing Rock on Island No.8—where granite boulders rise like sculpted steps above white sand and the current starts to dare you into the water.
These islands are exposed granite outcrops carved by wind and tide, part of Mu Ko Similan National Park and long used by local fishers and Moken communities. The park’s reefs host staghorn, brain and soft corals, and shallow channels concentrate garden eels, clownfish and parrotfish. The modern rhythm here is governed by conservation: the park is seasonally closed each year to let reefs recover.
On this full-day run you’ll stop at Christmas Point and Nam Chai Bay (Island No.9) for clear-water snorkeling, break for lunch at Princess Bay (No.4), then sweep past reef gardens at Islands No.5 and No.6. Guides provide masks, fins and safety briefings; transfers from Khao Lak are usually included, making this a low-logistics way to reach remote snorkeling spots.
Practical edge: expect an 8–9 hour day, bring reef‑safe sunscreen, sun protection and seasickness meds if you’re prone to motion‑sickness. Early-season mornings are calmest; keep a respectful distance from coral and nesting birds, and follow guide instructions—reef health depends on small choices. For a single-day taste of the Andaman’s underwater life, the speed catamaran balances quick transit with long, high-quality snorkeling stops.
