North of Highway 20, on the eastern edge of Lake County, the Indian Valley/Walker Ridge Recreation Area offers an abundance of recreational possibilities. Rolling chaparral covered hills dotted with oak and pine make an ideal setting for hunting, camping, bicycling, hiking, and equestrian use. Popular game animals include blacktail deer, black bear, quail, dove, and wild turkey. For wildflower enthusiasts, pockets of the rare Indian Valley Brodiaea and Adobe Lily can be found within the area.
The nearby Indian Valley Reservoir provides an excellent locale for fishing, boating, and swimming, although the water level can drop quite low in the summertime.
Access is via Walker Ridge Road off Highway 20. The reservoir is under the jurisdiction of the Yolo County Flood Control District. The 3,700-acre reservoir is open to all boating, with a 10-mph speed limit. Two launch ramps are available to the public. Visitors enjoy camping at tent and RV sties, picnicking, swimming, hiking, birding, other nature study, and hunting for waterfowl, quail, dove, turkey, pigs, and bear.
