Reva Gap and Picnic Spring campgrounds offer free or low-cost camping options in the northwestern corner of South Dakota, approximately 25-35 miles from the nearest towns. Sites sit at elevations between 3,000-3,500 feet, creating a distinct climate zone where summer temperatures typically range from 75-85°F during day and 45-60°F at night. Both campgrounds feature vault toilets but no running water, with sites situated in ponderosa pine forests characteristic of this transitional zone between prairie and forest ecosystems.
What to do
Stargazing sessions: The remote location of Picnic Spring Campground creates exceptional night sky viewing with minimal light pollution. "The stars shine bright at night," notes camper David B., who stayed for two nights in mid-September and enjoyed the stellar display.
Wildlife photography: Morning and evening hours offer prime opportunities for capturing elk, deer and small mammals. "While I was here in May I saw deer and elk," reports Jacob D. about his experience at Picnic Spring, adding that even in August the area remained relatively uncrowded.
Hiking to geological features: From Reva Gap Campground, take the moderate 2-mile trail to view unusual rock formations. "A not difficult path leads you upward to a beautiful view of The Castles formation in the Slim Buttes," explains Donna E., who camped there before the July 4th holiday.
What campers like
Spacious, private campsites: Sites at these campgrounds are positioned with considerable distance between them. "This campground is amazing. The geological formations around us are beautiful, and this place is isolated," writes Matthew S. about Reva Gap. "The campsites are spread out so you get tons of privacy."
Well-maintained facilities: Despite their remote location, both campgrounds receive regular maintenance. At Gascoyne Lake Campground, visitors appreciate the basic but functional amenities. "There are a couple picnic tables around in a field and you're right along the lake which had a beautiful sunset," states Abby M., who found this spot while traveling north.
Yurt camping options: For those seeking alternative shelter in the Reva area, yurt accommodations provide structure with minimal setup. "All of the 8 sites are very spread out and unique on their own," explains UnnamedAdventures about Picnic Spring, which features both traditional sites and alternative lodging options.
What you should know
No water sources: Bring all water needed for your stay. "No water, no electricity, no dump stations and no dumpsters for trash," warns David B. about Picnic Spring Campground. Plan accordingly with adequate water containers for your entire visit.
Remote location requires preparation: The nearest supplies are 25 miles away in either direction on Route 85. "Note the nearest groceries or any store for that matter is 25 miles away in either direction on Route 85," advises Danis O., recommending visitors arrive with all necessary provisions.
Cell service varies: Connectivity exists but fluctuates throughout the area. "I had 2 bars of LTE via ATT basically anywhere before the first camping loop. After that, 1 bar of 4G," reports Abby M. about her Reva Gap experience, noting service was sufficient for basic needs.
Tips for camping with families
Firewood availability: Some sites provide pre-cut wood from forest maintenance. "Several piles of wood available for firewood (resulted from clearing trees); you will need to split it, however," explains Leslie B. about her July stay at Picnic Spring Campground, noting the convenience for family campfires.
Site selection for weather protection: Choose sites based on seasonal conditions. "I stayed in 1st on the right. It was more exposed to wind and rain, but I preferred the layout. Other sites are more protected," advises Leslie B., highlighting the importance of selecting appropriate sites when camping with children.
Visit duration planning: Consider longer stays to fully explore the area's features. "I stayed there in mid-September for 2 nights," shares David B., adding that the spacious sites have "ample room to park more than one vehicle," making them suitable for families with multiple transportation needs.
Tips from RVers
Road conditions: Access routes to campgrounds involve unpaved sections but remain passable for most vehicles. "It was over 6 miles down a dirt gravel road. The road was fairly nice," reports Diana V. about her experience driving to Reva Gap Campground with a 23-foot trailer, confirming the route's accessibility.
Site dimensions: RVers report adequate space for larger rigs at most sites. "Spots were plenty big enough to fit multiple vehicles and campers," notes Gina G., who arrived at Picnic Springs after dark but still found the area accommodating for setup.
Arrival timing strategy: Mid-week arrivals significantly increase site selection options. "I gambled that the people who came in for the weekend would be gone and the ones who were coming for the next weekend would not be there for another day or two," explains David B., who arrived on a Tuesday around noon and found numerous available sites.
