Three kilometres of west-coast sand backed by the densest concentration of hotels, malls, massage shops and neon in southern Thailand. Patong is Phuket's engine room: it has the island's only real nightlife strip, its biggest mall, its most convenient beach, and a tolerance for excess that other beaches on the island have deliberately zoned out. It is also loud, built-up, aggressively commercial and, after dark on Bangla Road, relentless. The north end of the bay is noticeably calmer and cleaner than the middle. Whether you love it or loathe it is mostly a question of what you came for, and Patong does not pretend otherwise.
Who it's for: First-time visitors who want everything within walking distance — beach, food, shopping, a pharmacy, a dive shop and a bar — without renting a scooter. Anyone whose trip has nightlife in it: this is the only part of the island with clubs at any real scale. Families using the beach by day and the mall when it rains. People who want water sports, Muay Thai, or a cabaret show without a 45-minute drive.
