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

A valid hunting or fishing license is required for visitors 16 and older, with free camping available May 1–November 30 at first-come, first-served campgrounds featuring picnic tables, water access, and vault toilets.

High-clearance vehicles are recommended due to rough gravel and dirt roads, especially after rain or snow.
