The Oconee County is mostly composed of mountainous areas, so it is not surprising to find historic areas that are located in such terrains. The Stumphouse Mountain Tunnel is one of these notable areas.

The Stumphouse Mountain Tunnel is basically an incomplete railroad tunnel. It was built for the Blue Ridge Railroad of South Carolina in the Sumter National Forest after the proposal of Charleston residents so they can take a shorter route from the city to the Ohio river calle area. Work was started in 1856, but by 1859, when the state has already spent more than a million dollars on the project, it was still not complete. Work was abandoned as the local government refused to spend more on it.

Today, the Stumphouse Mountain Tunnel is a part of a public park featuring the Isaqueena Falls and the historic tunnel as its main attractions.
