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.
