The Town of Fairplay is a statutory town that is the county seat and the most populous town of Park County, Colorado, United States. Fairplay is located in South Park at an elevation of 9,953 feet (3,034 m). The town is the fifth-highest incorporated place in the State of Colorado. The population was 610 at the U.S. Census 2000. A historic gold mining settlement, the town was founded in 1859 during the early days of the Pike's Peak Gold Rush. It is the largest community in the grassland basin of Colorado known as South Park, sitting on the west edge of the basin at the junction of U.S. Highway 285 and State Highway 9. It is on a hillside just east of the Middle Fork South Platte River, near where Highway 9 ascends the river valley northward to Alma and Hoosier Pass. It is a quiet town, and the roads surrounding it have a low volume of traffic. Although it was founded during the initial placer mining boom, the mines in the area continued to produce gold and silver ore for many decades up through the middle of the 20th century.
