Board a longtail at Ao Nang and circle seven islands—white sandbars, coral-fringed snorkeling spots, a sacred cave, and a sunset buffet at Railay—finishing with a hopeful glimpse of bioluminescent plankton. Here’s what to expect and how to prepare.

Late afternoon light slants over limestone cliffs as a longtail boat slips from Ao Nang Pier, the Andaman Sea pulling at the hull like a curious hand. Riders trade hotel lobbies for wind on their faces, stepping across teak boards toward Tup Island’s shallow sandbar where the sea briefly becomes a walkway between islets.
