Bosque del Oso SWA Access provides entry to a 30,000-acre state wildlife area in Las Animas County with free camping in designated first-come, first-served sites (May-November) that include picnic tables, water access, and vault toilets.

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 access to coldwater stream fishing on the Purgatoire River and its tributaries through ten designated parking areas.
