Devils River State Natural Area protects one of Texas' clearest and least-developed river corridors, but it is not a single trailhead or campground. TPWD currently operates the Del Norte Unit and Dan A. Hughes Unit as separate reservation-only destinations.
The river attracts paddlers and anglers, while both units offer primitive backcountry experiences in exposed limestone and desert terrain. Extended river trips have additional access-permit requirements designed to control use and protect the river corridor.
Study the exact unit, road, check-in time and permit requirements before leaving Del Rio. Cell service is unreliable, summer heat is dangerous and an older 'Big Satan Unit' name in legacy data refers to property now identified by TPWD as the Dan A. Hughes Unit.
