Sirindhorn Dam (Khuan Sirindhorn)

History & Significance

Construction of the Sirindhorn Dam began in June 1968, with the foundation stone laid on February 2, 1969. King Bhumibol Adulyadej graciously granted permission to name the dam after Princess Maha Chakri Sirindhorn. The dam and its initial power transmission system were completed in 1971, and the King officially inaugurated the dam on November 27, 1971. In November 1972, the dam was handed over to the Electricity Generating Authority of Thailand (EGAT), which manages it to this day.

Highlights & What to See

• Nature Walkway & Glass Skywalk: A major highlight is the scenic walkway stretching over 415 meters from the Sirindharan Praphakon Building along the reservoir's edge. This glass skywalk offers breathtaking panoramic views of the water and surrounding nature.
• World's Largest Hydro-Floating Solar Hybrid Project: Spanning over 1,600 square meters on the reservoir's surface, this eco-friendly 45-megawatt solar project generates electricity from solar energy during the day and hydropower at night or during cloudy periods.
• Sirindhorn Garden: Established by EGAT to honor Princess Sirindhorn's 36th birthday, this beautifully landscaped public park was officially opened on February 6, 1991. It provides a peaceful, shady retreat for visitors.
