FR 1950 provides access to Costilla Creek in the Carson National Forest's Valle Vidal Unit, featuring a scenic canyon drive with multiple parking areas and fishing opportunities along the pristine waterway.

The well-maintained gravel road is accessible to 2WD vehicles for the first several miles and passes through a narrow rock-wall canyon before ending at a parking area near Costilla Reservoir.

Fishing requires special regulations (artificial flies/lures with single barbless hooks) and a New Mexico fishing license with Habitat Improvement Stamp.
