Earning the title of the largest reservoir in Thailand’s central region, Pa SakJolasid Dam was erected as part of the Maenam Pa Sak Royal Development Project, a royal initiative by His Majesty King Bhumibol. The earthen dam was granted its name by His Majesty who presided over its opening on 25 November 1999. The dam spans Lop Buri and Saraburi provinces, is an astounding 4,860 meters long, and has a capacity of 785 million cubic meters.
The dam has many uses: agricultural, industrial, and as a flood prevention measure. It is also an emerging tourist attraction, offering visitors the unique opportunity to travel across the reservoir by train. The railway leads to Pa Sak Basin Museum and a scenic lookout point above the dam. It is highly recommended to take the train in the cooler season between November and January. The train runs daily from 7.30 am-6.30 pm. The fare is 25 baht for adults and 10 baht for children. The dam itself is open from 7.30 am-6.00 pm.
