Planned around the city's original waterworks, Riverfront Park opened in 1983 for recreational usage. This park was planned around the site of the world's first electrically operated textile mill and the city's original waterworks and hydroelectric plant, the oldest one in the state and it is still operating. The park, which separates the Historic Columbia Canal and the Congaree River, is approximately 167 acres. A popular jogging/walking trail runs two and one half miles along the linear park and offers wonderful views of the river. There is also a beautiful brick amphitheater as well as a self-guided walkway by the old parts of the water plant. The park hosts several annual events such as Riverfest, Greekfest and several smaller concerts.
