Boulder Hill is a year-round, gravel forest road bridging Highway 16 to Sheridan Lake Road in the Black Hills. It can be accessed south of Rapid City on either of these roads. It is well-maintained and accessible by any vehicle. Boulder Hill also provides access to the Boulder Hill section of the Flume Hiking Trail.
Boulder Hill offers multiple small pull-outs suitable for camping along its path, suitable for one or two vehicles. There is also one large clearing near the Sheridan Lake Road side, which can accommodate several large vehicles or groups.
Boulder Hill's spur, 358.1H, provides access to private property and has no sights or obstacles to see.
