Bosque del Oso SWA Access provides entry to a 30,000-acre wildlife area in Las Animas County with ten designated parking areas that provide access to fishing waters including the Purgatoire River and its tributaries.

A valid Colorado fishing or hunting license (or SWA pass) is required for visitors 16 and older, with free camping available in designated first-come, first-served campgrounds (May-November) that include picnic tables, vault toilets, and water access.

Note that roads within the SWA are gravel and dirt with rough conditions in some areas, so high-clearance vehicles are recommended, and access is restricted December-April to licensed big game hunters and one companion.
