Ao Hin Khok

Ao Hin Khok is a small beach on the eastern coast of Ko Samet island in Phe Subdistrict, Mueang Rayong District, Rayong Province, Thailand. Located within Khao Laem Ya–Mu Ko Samet National Park, it lies between Ao Phai and Ao Nuan. The beach is notable for its combination of white sand and distinctive rock formations, relatively quiet atmosphere compared to busier beaches, and clear shallow water suitable for wading and photography.

Visitors can expect a small, relatively quiet sandy cove interspersed with distinctive boulders and rock formations along the shoreline and in shallow water. The beach is backed by low vegetation and small resorts and restaurants. The setting is more secluded than Hat Sai Kaew, with clear water for wading and swimming, areas for sunbathing and photography, and easy walking access to neighboring beaches Ao Phai and Ao Nuan along coastal paths.

Part of Khao Laem Ya–Mu Ko Samet National Park, established in 1981 to protect the coastal and island ecosystems of Rayong. Ko Samet was traditionally a fishing and secluded retreat island before developing as a national park tourism destination.
