Fed by numerous clear springs within the region's karst topography, the Devils River is one of the most ecologically intact rivers in Texas. From the hilltops and water's edge of the State Natural Area, visitors can revel in the sight and sound of the river's waters tumbling over limestone past rugged ridges, canyons and grassy banks, giving life to diverse plants and wildlife. Visitors can enjoy day hiking, primitive camping, nature viewing, mountain-biking, horseback riding, and guided rock-art tours by appointment.

Access to the river (0.9 miles from the parking area) is by hiking, biking or pre-arranged tour only; no public vehicle access permitted. Paddler put-in for canoes and kayaks only may be available by special appointment. No motorized boats are allowed. Devils River State Natural Area is unique in that it is very primitive and isolated with few amenities and no landscaped playgrounds. Visitors should bring their own food and water and be prepared for a rugged wilderness experience.
