Cumbres de Monterrey & Rayones Canyon Pass - NL-20 / NL-58
Slices through the towering limestone monoliths and sheer slot canyons of Cumbres de Monterrey National Park. Begins near the Cola de Caballo waterfall, snaking through deep alpine canyons to the secluded walnut oasis of Rayones, then climbing a dizzying cliffside canyon road up to the high Altiplano basin of Galeana beneath Cerro del Potosí (the highest peak in Northeast Mexico). Road Quality: Mixes winding mountain asphalt with rough, unpaved gravel shelf sections and rock-cut overhangs; requires good throttle control and dual-sport tires. Safety & Military Checkpoints: Nuevo León state police (Fuerza Civil) checkpoints near Santiago; narrow slot canyons subject to flash floods and rockfall during summer storms; sound your horn on blind one-lane cliff corners. Fuel Range: Full Pemex stations in Santiago and Galeana; no reliable fuel in the deep canyon corridor between; ensure 85-mile range.
