About Bhumibol Dam

Bhumibol Dam is a large hydroelectric dam in northern Thailand on the Ping River, named for King Bhumibol Adulyadej and recognised as an important infrastructure project for power generation and water management in the region.

The site includes the dam structure, a substantial reservoir and associated infrastructure; visitors may view the structure from designated viewpoints and a visitor area that explains the dam’s purpose. The reservoir and surrounding landscape are used for limited recreation and sightseeing.

Constructed in the mid-20th century as part of national efforts to expand hydroelectric power and regulate river flows, the dam has played a long-term role in regional development, irrigation and energy supply. It remains a notable example of large-scale hydraulic engineering in Thailand.

Located in Tak Province in northern Thailand, the dam sits on the Ping River and is reached by road from nearby towns in the province.

  • Significance: Named after King Bhumibol Adulyadej, the dam is a major hydroelectric and water-management structure for northern Thailand and is visible from public viewpoints and a visitor area.

Exploring Bhumibol Dam

Located around 60km north of Tak city in Sam Ngao District, this is the highest dam in Southeast Asia at 154 metres, and the reservoir behind it backs up the Ping River for around 140 kilometres, almost as far as Hot in Chiang Mai Province. It is the biggest dam in Thailand and ranks as one of the top hydroelectric-producing dams in the world. Built of concrete, it cuts an arc across the Ping River between the Khao Yanhi and Khao Kaew mountain peaks, and the entire project is owned and operated by the Electricity Generating Authority of Thailand. Thai visitors occasionally stop by just to admire the dam’s size, though few foreigners venture here.

The scenic surroundings warrant spending a night near the reservoir. Options include accommodation run directly by the electricity plant, while a local resort enjoys expansive views of the countryside and has ample guest facilities. Fishing and all manner of water-borne activities are possible, including boat tours along the length of the reservoir, and there is also a golf course. The government has invested heavily in the project and works hard to generate enthusiasm among tourists.
