The Permian Reef Trail climbs the north side of McKittrick Canyon to the top of Wilderness Ridge, providing sweeping views into South McKittrick Canyon. At the park boundary, and state line, the trail continues into New Mexico and the Lincoln National Forest. The slopes above the canyon face south, thereby receiving full sun all day, hence the hike is best avoided during hot periods in summer.

Distance: 4.0 miles (6.4 km) to top of ridge; 4.5 miles (7.2 km) to Wilderness Ridge Campground; 4.8 miles (7.7 km) to park boundary (one way distances)

Elevation Change: 2,000 feet

Time Estimate: 5-7 hours

Difficulty: Strenuous

In addition to providing sweeping views of the landscape, the trail was designed to showcase the Permian age geologic and fossil features preserved in the park. For those with a serious interest in Geology, a detailed guidebook for the features seen along the trail from the Texas Bureau of Economic Geology can be purchased at the visitor center.
