San Juan National Forest encompasses about 1.8 million acres in the southwestern corner of Colorado. Terrain ranges from high-desert mesas to alpine peaks, with thousands of miles of back roads and hundreds of miles of trails to explore. These federal lands are managed for multiple uses and visitors are asked to respect each other and the natural resources. The San Juan National Forest Headquarters is located in Durango, Colorado, with district offices in Bayfield, Dolores and Pagosa Springs.
