A visitor information sign at Big South Trailhead (#944). Directional sign to trails is on the left.

The Big South Trail enters the Comanche Peak Wilderness a half-mile from the trailhead. Nineteen designated campsites are located in the next 7 miles. Sites are on a first-come basis. The Flowers Trail (#939) intersects from the east shortly before the trail fords the Poudre River. The river crossing is difficult or dangerous depending on the time of year, the amount of runoff, and the water flow controlled by Long Draw Reservoir. The Big South Trail continues south to join the Corral Creek Trail (# 989) with four more designated sites and provides access to Rocky Mountain National Park via the Poudre River Trail. The Big South trailhead accommodates approximately 19 vehicles.
