Bosque del Oso SWA Access provides entry to a 30,000-acre state wildlife area in Las Animas County with two main access points—one near Zamora (west entrance) and one in Weston (east entrance)—offering free camping in designated first-come, first-served sites with picnic tables, water access, and vault toilets.

A valid hunting or fishing license is required for visitors 16 and older, and the area is open May 1–November 30 for general public access, with gravel and dirt roads requiring high-clearance vehicles, especially after rain or snow.

The Purgatoire River and its tributaries provide fishing opportunities across ten designated parking areas, while camping is limited to 14 days per visitor with sites available from May through November.
