Sometimes, imagination can create an atmosphere of happiness. Just like relaxing by a massive reservoir, which sometimes evokes the feeling of lounging by a lakeside. The Rattana Reservoir, or Ban Rattana Reservoir, offers just that experience. With a vast capacity of 2,020,000 cubic meters and spanning an area of 1,600 rai, it features a spillway building 15 meters wide, alongside an earthen dam that stands 15 meters high and stretches 250 meters long. This site meets the needs of travelers who enjoy the refreshing coolness of water. In the evenings, the ambiance here is incredibly pleasant with gentle breezes blowing, and it provides a beautiful view of the sunset. Occasionally, you may even witness a rare sight of mist enveloping the area around the reservoir. To find this location, take Highway 2325 and go about 100 meters past kilometer 5; the entrance to the reservoir will be on your left. Continue along the pathway for approximately 400 meters. For those interested in visiting, it is advisable to contact the Phetchabun Provincial Irrigation Office in advance at 0 5691 1156.
