The tunnel was manually excavated over a period of three months by members of the Communist Party of Malaya.
At its operational peak, the facility was designed to accommodate up to 200 people during air raids.
The complex includes nine original entry and exit points concealed by dense jungle canopy.
The tunnels were utilized as a strategic base until the Communist Party signed a peace treaty with the Thai government in 1987.
The structure was specifically engineered to withstand aerial bombardment and heavy artillery during the regional insurgency.
Historical records and photographs displayed inside were donated by former members who transitioned to civilian life in Betong.
Piyamit Tunnel is a historical underground network constructed in 1977 by the Communist Party of Malaya to serve as a base for operations and protection against airstrikes. Located within the lush terrain of Betong, Yala, the tunnel system stretches approximately one kilometer and is carved into the mountainside. The site features multiple exits and entry points, previously used for concealing weapons and storing food supplies. It currently functions as an open-air museum detailing the clandestine life of the Malayan National Liberation Army. Visitors can walk through the original tunnel structures which remain structurally intact. Exhibits include historical photographs, recovered relics, and life-sized mannequins demonstrating past insurgent activities. The surrounding area is heavily forested, contributing to a humid and cool microclimate within the underground passages.
