Trailhead Directions

From Albuquerque go North on I-25 to Bernalillo. Go west on US 550 from Bernalillo to milepost 25 which is about 1.5 miles beyond San Ysidro. There is a small parking area beyond the west end of paved pull off area on the right in a fenced parking area marked “San Ysidro Trials”. Pull in there and PARK (0.0 mi).

Actual Hike

There is a fence pass through at the west end of the parking area. Go through the pass through and hike the road which curves to the north and up the hill. The road drops down into an open motorcycle event gathering area before a arroyo. At this WYE (1.2 mi) bear right and cross the arroyo and follow the path which goes slightly north of east. LEAVE (1.3 mi) the path going right across a small wash and up onto the rim of a large digging. Pass around the south side of the digging and pick up a path. Follow the path, staying on the north side of the low hills. Proceed downward to CROSS (2.2 mi) at the lower end of a small canyon which extends northward. Go north, staying near to the low hill on your right until you see a very rocky up slanting expanse. Travers upward over this area toward EAST CANYON (2.9 mi) where there is a view into a deep gorge. Go northwest to an east/west running fence, which is the boundary line for Jemez Pueblo land. Follow the fence to the CENTER CANYON (3.4 mi) and turn south along the canyon until MONKEY HEAD (3.5 mi) is reached. Cross the canyon and then head NORTH (3.5 mi) along the canyon to the Pueblo boundary fence. Go west, then TURN SW (4.2 mi) moving away from the fence across the rocky section to the WEST CANYON (4.6 mi) and cross the canyon. Go north along the canyon to PUEBLO FENCE (4.9 mi). Turn back and follow the canyon which turns into a wash until you reach the motorcycle event gathering area. Return to parking on the road.


This is BLM land. A motorcycle club has an agreement with the BLM to use the area for trials. A series of courses have been laid out in the area. The area is seldom used by the cyclists, who have access to the area on the gated road during events.
