Circuito Cerros Chichinautzin, Huitzilac

The trailhead sits near Fierro del Toro, reached by private vehicle from Huitzilac town center or from Cuernavaca and Mexico City via Federal Highway 95, following local signage into the Corredor Biológico Chichinautzin. No permit is required for day hiking in this section of the corridor, and informal parking is available near the trailhead. The circular route covers 7.4km with moderate rolling elevation gain through pine and fir forest sitting at roughly 2,900-3,000m altitude, making the thin air and cool temperatures a bigger factor than the terrain's technical difficulty. The path surface alternates between packed dirt and loose volcanic stone, with sections of scree on some of the steeper rolling sections; there is no significant exposure, but footing requires attention on the volcanic rock. Landmarks include several small clearings used for birdwatching, since the corridor is known for its resident and migratory bird populations, and a mid-route high point offering views across the forested volcanic terrain toward the Mexico State border. Hikers looking for a shorter outing can turn back at this high point roughly halfway around the circuit rather than completing the full loop. There are no refuge huts or maintained water sources along the route, and the altitude means temperatures can drop quickly if weather turns, even outside the rainy season. The forest canopy provides shade for most of the walk, a contrast to the exposed sections found on lower-altitude trails elsewhere in Morelos. The loop returns to the Fierro del Toro trailhead via the same corridor, closing the circuit through similar forest terrain.
