Ao Wong Duean

Ao Wong Duean is a crescent-shaped sandy beach on the eastern coast of Ko Samet in Phe Subdistrict, Mueang Rayong District, Rayong Province. Located within Khao Laem Ya - Mu Ko Samet National Park, it is known for its calm, clear water, fine white sand and relatively tranquil atmosphere compared to Hat Sai Kaew. The bay is lined with resorts and restaurants and is popular for swimming, sunbathing and evening fire shows.

Visitors can expect a 500-meter curved bay of white sand and calm turquoise water on the east side of Ko Samet. The beach is lined with mid-range to upscale resorts, beachfront restaurants and bars. The sea is generally calm and suitable for swimming and kayaking. The atmosphere is more relaxed than the island's northern beaches, with sun loungers, dining areas and fire shows in the evening. Access is via footpaths from the island's main road and via songthaew from the piers.

Ko Samet and surrounding islands were designated as Khao Laem Ya - Mu Ko Samet National Park in 1981 to protect the archipelago's beaches, coral reefs and forests. Ao Wong Duean has developed as one of the island's main resort bays within the national park.
