Within Custer National Forest, Picnic Spring Campground sits atop a Ponderosa pine-capped butte in the Cave Hills, accessible via approximately 6 miles of gravel road from Highway 85. This Forest Service campground operates on a first-come, first-served basis with 10 spacious sites spread across the forested hilltop.
The layout prioritizes privacy, with sites positioned so campers rarely see their neighbors. David B. notes the campground has "no water, no electricity, no dump stations and no dumpsters for trash," making this a pack-it-in, pack-it-out operation. Each site includes a fire ring, picnic table, and room for multiple vehicles. Clean pit toilets serve the campground, and split firewood from tree clearing projects is available at most sites.
Small canyons border much of the campground, and the Cave Hills contain numerous trails and roads for exploration, though campers should consult Forest Service maps to stay on public land. Wildlife sightings include deer and elk, particularly during early morning and evening hours. Cell service works reliably for Verizon, T-Mobile, and AT&T users.
The gravel access road handles big rigs up to 26 feet, though Jacob D. describes the route as "pretty sketchy to find." Most visitors arrive Tuesday through Thursday to avoid weekend crowds, though even holiday weekends see only moderate use. The nearest services are 25 miles away in either direction on Highway 85. A natural spring provides untested water that requires boiling before consumption.
This remote campground works well for campers comfortable with primitive conditions who want space between sites and access to backcountry exploration in one of North America's oldest geological formations.
