Ao Cho

Ao Cho is a small sandy bay on the eastern coast of Ko Samet island in Phe Subdistrict, Mueang Rayong District, Rayong Province. Located within Khao Laem Ya–Mu Ko Samet National Park, it lies south of the main Hat Sai Kaew area. The beach is known for its curved white sand, clear shallow water, coral fragments and quiet atmosphere compared to northern beaches. It is lined with resorts and restaurants and is popular for swimming, sunbathing and snorkeling.

Visitors can expect a quiet, curved sandy cove about 300-400 meters long with fine white sand, clear turquoise water and scattered coral and rocks at both ends. The bay is lined with low-rise resorts, beachfront restaurants and bars with sun loungers and umbrellas. The atmosphere is more relaxed and less crowded than Hat Sai Kaew. Areas for swimming, sunbathing, beach walking and snorkeling near the rocky headlands are accessible, with views of nearby islands and calm seas in the dry season.

Ko Samet is associated with the classic Thai epic Phra Aphai Mani by poet Sunthorn Phu, who set part of the story on the island. Ao Cho itself developed as a resort bay in the late 20th century after the establishment of Khao Laem Ya-Mu Ko Samet National Park in 1981.

The bay lies within Khao Laem Ya-Mu Ko Samet National Park, reflecting Thailand's marine conservation and island tourism culture. It is part of the traditional fishing and island community of Phe Subdistrict and retains a laid-back island resort character.
