This dam, located around 60km north of Tak city in Sam Ngao District, is the highest in Southeast Asia at 154 meters and the reservoir behind it backs up on the Ping River for around 140 kilometers, almost as far as Hot in Chiang Mai Province.
It is the biggest dam in Thailand, and it ranks as one of the top hydroelectric producing dams in the world.
Named after the King of Thailand, the dam is built with concrete, and cuts an arc across the Ping River between Khao Yanhi and Khao Kaew mountain peaks. The entire project is owned and operated by the Electricity Generating Authority of Thailand, and 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. Visitors have a few options, including accommodation run directly by the electricity plant; 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. There’s also a golf course here. The government has invested plenty of resources into this project, and they work hard to generate enthusiasm among tourists.
Getting There
The easiest way by far to get to this dam is with a rented vehicle. Drive north from Tak on Highway 1 for about 40km and then turn left on the road to Sam Ngao. Irregular songthaew go there from Tak, but be prepared for a long wait.
