Duncan Trailhead provides wilderness access to the Gunnison River via a challenging 1. 5-mile trail with an 840-foot elevation drop, featuring steep loose scree in the final 0. 5 mile and three hiker camps at the river.

The trailhead offers picnic tables, restrooms, and a self-serve fee station ($3 day-use or $10-15 for camping); access requires a high-clearance 4WD vehicle on a rough 2-mile road that is impassable when wet.

This popular fishing access point is not recommended for horses due to steep terrain, and wilderness permits and registration are required for all visitors.
