It is located within Table Rock State Park in Pickens County, South Carolina.

The summit of the mountain is accessible by hiking trails, the shortest of which is 4.2 miles one-way and begins at the Table Rock State Park Nature Center.

It's mainly an eroded mountain of gentler slopes with a summit completely cloaked, principally in poplar, oaks, and other hardwoods.

There is some very steep forest terrain on the eastern side of the peak, Bald Rock, where there are some cliffs and slopes.

In the late 1990s, some 600 plus prehistoric petroglyphs were discovered at Pinnacle Mountain.
