Morning light floods the Andaman as a speedboat slips away from Phuket’s harbor, the sea daring you forward toward the Similan Islands. On this full-day run you hop between four park isles—Payu (No.7), Koh Miang (No.4), Koh Ba Ngu (No.9) and Koh Similan (No.8)—diving into clear, blue water, drifting over coral gardens and climbing a short trail to the famous Sail Rock viewpoint.

Morning light floods the Andaman as a speedboat slips away from Phuket’s harbor, the sea daring you forward toward the Similan Islands.

The islands are part of Similan Islands National Park, protected since the early 1980s. Granite outcrops worn smooth by wind and waves tower above narrow white beaches; under the surface, ancient coral plates and boulder-strewn reefs host parrotfish, anemonefish and occasional green sea turtles. The Moken and southern Thai fishing culture have long read and respected this coastline; today the park balances tourism with conservation through admission fees and visitor limits.
Practicalities shape the day: expect 8–9 hours including transfers, hotel pickup, and two ~1h15 boat legs. Snorkeling times are split across sites with a beach lunch included on Koh Miang. Gear basics (mask, snorkel) are supplied, but personal fit matters. Bring reef-safe sunscreen, a light long-sleeve or rash guard for sun and wind, and a small dry bag for electronics. Seas can be choppy—if you get motion sick, take precautions before departure.
Plan for an early start, respect coral (no touching or standing), and listen to guides about currents and safe swim zones. The payoff is immediate: sunlight freckling coral plates, the current nudging you past a hawksbill shadow, and that nearshore viewpoint that makes the whole day click into place.
