The boat slides away from Phuket’s harbor before dawn, the first light cutting across the Andaman Sea. By mid-morning the Similan Islands appear as granite silhouettes that rise from blue water; white beaches and rounded boulders give way to coral gardens fringed by current-swept channels. The islands demand movement—swells push the hull, reef flats challenge a snorkel, and a shoreline view dares you to climb a short rocky trail for a panorama.
