Numerous roads penetrate the range, although most are closed in winter.
From Highway 395, at the south edge of Alturas, go east on County Road 56. Modoc National Wildlife Refuge is directly to the south, and County Road 115, on your right in .6 mile, will take you to the refuge headquarters and auto tour route. Juniper Titmouse is an uncommon resident of the juniper woodland north of the reservoir. The reservoir itself is good for Clark's Grebe in summer, and for shorebirds during migration. From Alturas, take County Road 56 east.
