Trail guide
Dog Canyon Trail is a 4-mile out-and-back from the paved pullout on U.S. 385, crossing open desert before entering a break in the Deadhorse Mountains. The park estimates 2–3 hours and about 50 feet of elevation change. Choose it for the limestone walls at the end; most of the walk is a fairly level desert approach.
Follow the cairned sand-and-dirt tread across sparse desert brush. Around 1.5 miles in, it reaches a normally dry wash and a metal sign. Turn left into Dog Canyon; the right fork continues toward Devil’s Den. The signed junction is easy to miss on the return, so take a moment to register it before heading into the canyon.
The last half mile follows a rocky drainage, where footing gets uneven and unstable. High limestone walls close in around the wash; the route passes between the cliffs and out the other side. Most hikers turn around where the canyon ends and retrace the same route. From the roadside, the canyon’s cleft stands out across the open plain; farther in, the close walls make a striking frame around the trail.
The approach has little shade and only scattered creosote, cactus, and grasses. Bring water and sun protection; the park recommends about a liter per person for each planned hiking hour and cooler early or late starts. After good rain, clay mud can clump on shoes and make walking difficult.
Use the signed Dog Canyon and Devil’s Den pullout, 4.5 miles south of the Persimmon Gap entrance. It is paved and has room for about five vehicles. Dogs and other pets are not allowed on park trails.
