Paso de Cortés Mountain Biking

Paso de Cortés Mountain Biking follows a network of high-altitude dirt roads around the Paso de Cortés visitor center in Izta-Popo Zoquiapan National Park, on the saddle between the Popocatépetl and Iztaccíhuatl volcanoes in Puebla, Mexico. The route covers about 20 km round-trip at elevations above 3,600 meters, making sustained fitness and some acclimatization to altitude more important than technical riding skill, since the roads themselves are wide dirt tracks rather than singletrack trails. Riders should be prepared for thin air affecting breathing and stamina even on moderate grades, and those arriving directly from sea level are advised to spend at least a day acclimatizing in Puebla city, which itself sits above 2,100 meters, before attempting the ride. Local rental operators at the park entrance provide a mountain bike and helmet for the ride; riders should bring layered clothing, since temperatures at this elevation swing sharply between cold mornings and strong midday sun, along with sunscreen and a windbreaker. Bikes are rented from local operators based at Paso de Cortés who maintain their fleet for the specific demands of the high-altitude dirt roads and can advise on route options depending on rider fitness and current conditions. Riders should carry sufficient water, since there are no services along most of the route, and pace themselves conservatively given the altitude. Access to the pass can be restricted or closed by park authorities during periods of heightened volcanic activity from Popocatépetl, so current conditions should be confirmed before setting out. The roads are firmest and driest from November to April, when the dry season keeps the dirt surface stable, while the summer rains can leave sections muddy or rutted.
