A low-slung longtail cuts a wake off Big Buddha Beach as the mainland of Koh Samui slides behind you—the island’s crescent of sands and palms shrinking into a horizon of blue. The morning air tastes of salt and diesel; guides pass out snorkel masks and paper towels while the boat’s engine finds a steady rhythm. Over seven hours you’ll skim Chaweng’s bright coast, sight Grandfather and Grandmother rock, and anchor on Koh Tan—called Green Peace Island—for lunch, snorkeling, and a stretch of real quiet.
