Sierra de Manantlán Biosphere Circuit

The Sierra de Manantlán Biosphere Reserve harbors some of Mexico’s last intact cloud forests, accessible only via a network of abandoned logging roads that switchback up volcanic ridges between 5,000 and 8,000 feet. This remote circuit connects the Colima border near Comala with the Jalisco highlands around Autlán de Navarro, passing through the original wild teosinte habitat—the ancestor of modern corn. Key challenges include the technical descent into Barranca de Manantlán and multiple stream crossings during the transition between pine-oak and tropical dry forests.

This is expert-level territory requiring serious 4WD capability, winch, and navigation skills as GPS often fails in the dense canopy. Roads can be impassable during rainy season (June-October). Best attempted in dry season with multiple vehicles and camping gear for 3-4 days. No services exist within the reserve—carry extra fuel, water, and emergency supplies. The reward is accessing one of Mexico’s most biodiverse and least-visited wilderness areas.
