Hopper Mountain National Wildlife Refuge sign

A high mountain valley encircled by deep canyons, steep ridgelines, and rocky pinnacles, Hopper Mountain National Wildlife Refuge is the gateway into California condor country. The refuge is an outpost on the edge of an unforgiving terrain where California condors safely forage, nest, and roost. Under the wing of these majestic birds, the refuge supports healthy examples of oak woodlands, grasslands, chaparral, coastal sage scrub, seasonal wetlands, riparian areas, and some of the last remaining intact stands of California black walnut.
