The California Department of Fish and Wildlife (CDFW) is pleased to announce the re-opening of the Knoxville Wildlife Area and Cedar Roughs Wildlife Area, both in Napa County. The August 2020 LNU-Lightning Complex Fire consumed the entire 21,500-acre Knoxville Wildlife Area and both units of the Cedar Roughs Wildlife Area (414 acres).
The public is asked to remain vigilant of potential hazards such as falling trees and rocks, and to confine use to established old ranch road trails. Potential for debris flow is high along the northern section of Berryessa-Knoxville Road and in the Long Canyon area during heavy rain events. To protect public safety, this may prompt subsequent closure of the Knoxville Wildlife Area.
