Ao Phrao

Ao Phrao is a crescent-shaped bay and beach on the western coast of Ko Samet Island in Phe Subdistrict, Mueang Rayong District, Rayong Province, within Khao Laem Ya–Mu Ko Samet National Park. Known for its fine white sand, clear turquoise water and west-facing sunset views, it is quieter than the island's busy east coast beaches. Fringed by resorts and low forested hills, it offers calm waters for swimming and snorkeling.

Visitors can expect a curved 500-600 meter white-sand bay on the west coast of Ko Samet facing the Gulf of Thailand, bordered by forested hills and resort properties. The beach has clear, generally calm water suitable for swimming and wading, with sun loungers and resort restaurants along the shore. The setting is quieter and less developed than Sai Kaew Beach, with open sunset views, opportunities for photography, snorkeling and kayaking, and access via island songthaew or motorbike from the main pier area.

Ao Phrao lies within Khao Laem Ya–Mu Ko Samet National Park, established in 1981 to protect the islands and coastline of Rayong. The bay gained national attention in July 2013 when an oil spill affected its shoreline, leading to a major cleanup and restoration effort.
