Take Highway 434 south from Angel Fire for four miles. Turn right on County Road B-29 which becomes Forest Road 76
. Almost two miles past the South Boundary Trail #164 trailhead, turn right onto Forest Road 153. The trailhead is 0.4 miles up FR153 on the right.
Rio Chiquito Trail #121 consists of two sections, with two different ride-feels.
The upper section between Jarocita Park and Borrego Crossing is typically referred to as the "Jarocita Trail" and is often ridden as a loop from the South Boundary Trail via FS Road #438 East
and Quintana Pass. This trail is largely forested, fairly steep in sections, and the most fun riding from East to West.
The lower section connects Borrego Crossing at FS Road #438 East
to what is referred to as Rio Chiquito Campground on FS maps at the end of Forest Road 437CG
(it's an wide open meadow with no facilities, but great camping). This section is trail parallels the Rio Chiquito on the north side, passing endless beaver ponds and occasionally disappearing through cow-pocked meadows. The ride is less steep than the upper section, and fairly mellow except for one section where it breaks through a rocky stair-step of cliff and scree where you might be more comfortable walking.
