About
Cartwright Ridge Campground occupies the north end of Sage Hen Reservoir in Idaho's Boise National Forest. The setting is a mixed conifer forest of Ponderosa pine, Engelmann spruce, Douglas fir, and grand fir at 4,800 feet elevation. Most sites offer shade, and some have partial lake views. Wildlife in the area includes deer, elk, black bear, goshawk, woodpeckers, and boreal owls. The campground is part of a recreation complex at Sage Hen Reservoir that includes multiple campgrounds. A boat ramp and dock within the campground provide easy access for motorized and non-motorized boating. The 4-mile Sage Hen Reservoir Trail loop is accessible from the campground for hiking. ATV and motorcycle trails are also accessible from the area. The campground is primitive with vault toilets only. There is no potable water, so campers must bring their own water supply. Access requires approximately 19 miles of travel on Forest Service roads 618, 626, and 614 from the town of Ola.
