Rio Arriba County's climbing area, known as the Brazos, San Juans, sits in northern New Mexico, about 4.5 miles from Crowther Cow Camp. It is a small, two-route traditional climbing area, and both of its named routes are trad, with grades ranging from 5.7 to 5.10. The two routes are Cat Burglar at 5.7 and Roybal's Horrendous 5.10 Offwidth at 5.10. The offwidth is the more challenging of the two, and both are rated for traditional climbing. For timing, summer is the warmest stretch. Typical averages from a nearby weather station at Tres Piedras show July highs around 81°F with lows near 48°F, while winter highs sit in the upper 30s. That station sits roughly 1,600 feet lower than the climbing area, so temperatures here run cooler. The station's figures are typical averages from 1991 to 2020. Other spots within about 10 miles include the Rio Brazos, a canoeing route about 2 miles away, the Tony Marquez Trail (41) hike at 7.5 miles, and Trout Lakes campground at 9.6 miles.
