Beyond Bangkok, from the estuary of the Chao Phraya River, the East Coast unfolds in a series of bays and beaches to the Thailand-Kampuchea border. Many popular resorts, including Pattaya, Asia's premier beach resort, occupy a coast characterised by cliff-hidden bays, palm-fringed beaches, innumerable fishing communities, lovely islands and largely tranquil Gulf waters. The region is rich in natural resources, including rubber, rice, fishing, orchards and gemstones, and scenically arresting with several national parks containing waterfalls, virgin forest and uninhibited, remote islands.
