Bosque del Oso SWA Access provides entry to a 30,000-acre wildlife area west of Weston with designated parking areas and free camping (May-November) along the South Fork Purgatoire River and its tributaries.

A valid Colorado fishing or hunting license is required for visitors 16 and older, and high-clearance vehicles are recommended due to rough gravel and dirt roads.

The area offers 10 designated fishing access points and first-come, first-served campsites with picnic tables, vault toilets, and water access.
