Batam is a small island in Indonesia’s Riau Archipelago in the South China Sea. A short boat ride from Singapore, it’s a free trade zone with multiple busy ports. It’s also known for its beaches, nightlife and malls offering duty-free shopping. Bustling Nagoya is Batam’s main city. Upscale resorts in the shoreline area of Nongsa offer golf courses and water sports, including windsurfing, parasailing and jet skiing.
