Tanjung Rhu is one of Langkawi's most beautiful beaches, set on the quieter northern side of the island with pale sand and limestone islets offshore. It feels more spacious and less built-up than Pantai Cenang, especially outside peak times.
The scenery is the point: shallow water, mangrove edges, and views toward the karst islands around the Kilim area. Bring shade and supplies if you plan to linger, and check access conditions because parts of the beach sit near resort-managed land.
