Later it was bought by a man who had a dream to build an amusement park. The amusement park, particularly its carousel, entertained residents of the area for many years. Unfortunately, it was destroyed by a fire.
For a brief period before it became a National Park, an electric company purchased the land and hoped to develop a power plant. However, nothing was ever built.
The land was eventually bought by the Potomac Edison Power Company (PEPCO) with plans to construct a hydroelectric dam. However, due to the hydrology and geology of the area, the site at Great Falls was determined to be unfit for hydroelectric development. Fairfax County Park Authority leased the land and continued operating as a park, allowing the public to visit the Great Falls and ride the carousel. In 1966, through an agreement with Fairfax County, the National Park Service acquired the lands, totaling 800 acres. In 1968 the visitor center was built.
