Gravel pads and open desert sky define the experience at Cottonwood CJ Strike Reservoir, a utility-managed campground on the Bruneau arm of CJ Strike Reservoir outside Bruneau, Idaho. The layout is built around boat access: a marina, boat ramp, and fishing dock with pole holders sit near the sites, and some spots along the water allow small-boat launches directly from camp. This is a campground organized around reservoir recreation, and campers without a boat or fishing gear will find little else to do on site.
Shade is limited and worth planning around. Sites near trees, particularly site four, hold shade through most of the day, while exposed sites can get brutally hot in summer. Temperatures above 110°F have been recorded here, and the lack of tree cover is a consistent theme across reviews. Sites closest to the water feel close together; those farther back give more room between neighbors. Flies can be a significant nuisance, especially in late summer. Cell service is spotty, with T-Mobile users reporting one bar or none.
Each site includes a picnic table and fire pit with grate, though fire restrictions may apply during high-risk periods. Full hookups with electric, water, and sewer are available, making this a functional base for RV and trailer campers. Vault toilets are on site, along with potable water at multiple spigots and dumpsters for trash. As Kyle J. puts it, the campground is "great for trailer campers, not great for tents." Campers wanting more shade or trail access might consider Cove at CJ Strike Reservoir - BLM as an alternative, or browse camping near Bruneau for other options in the area.
