Blue Lakes are part of a cluster of lakes 12 miles south of Highway 88 at Hope Valley. Operated by Pacific Gas and Electric Company, the lakes serve as water storage for downstream hydro-electric plants. Four main campgrounds, plus an expansion campground are open as soon as the road is plowed free of snow in early summer.
The lakes offer boating, swimming, and fishing. Unimproved boat ramps are available at both Upper and Lower Blue lakes. Small boats are allowed on the lakes. Anglers have great success in both the upper and lower lakes as well as in some of the nearby lakes. Hikers are rewarded with fields of wildflowers and an abundance of wildlife.
