Excellent hiking.
Travel northwest on US 550 from Bernalillo, NM, past San Ysidro (23 miles from Bernalillo). Continue northwest along US 550 about 20 more miles to the junction with County Road 279 to the west (left). A green highway sign (labeled "San Luis - Cabezon - Torreon") marks the County Road 279 turnoff. This paved road passes through the small village of San Luis, after which the road turns to gravel and dirt. Travel on this dirt road approximately 18 miles, crossing the bridge over the Chico Arroyo, until the road splits - County Road 279 continues south to Guadalupe and BLM Road 1103 begins west. Travel on 1103 for about one mile, until County Road 25 splits to the north. BLM Road 1103 continues to the mesa top of the Ignacio Chavez Grant.
