Beyond PR 3A, several drives branch off as loops accessing campsites, staff residences, and other park facilities.

The road makes a sharp curve and a steep upward grade before ending at Indian Lodge 1.2-mile (1.9 km) west of the intersection with PR 3A.

Landowners finally agreed to donate land for the park in 1933 to boost the local economy devastated by the Great Depression.

The road travels from a junction with PR 3 to the border of the state park, and provides access to a hiking trail leading to Fort Davis National Historic Site.

After leaving the campground, the road begins steeply ascending the ridge between Keesey and Hospital canyons on a climb requiring several switchbacks.
