Approximate location — plotted from published sources, not a site visit, and not a guarantee of access.
On a steep ridge above Shasta Lake in Shasta-Trinity National Forest, Hirz Mountain Lookout is a fire lookout rental. A rocky dirt road climbs to a locked gate; the final approach is on foot. The cabin-style lookout rents through Recreation.gov as a destination overnight, not merely a drive-by viewpoint.
