This is a primitive forest park 6 miles West of Custer (half-way between Custer and Jewel Cave). There's no hook-ups and only pit-toilets, but it's peacefully located in thick forest. Sites are dirt, mostly level with bench and fire-pit. Many will accommodate big-rigs, but some are a tight tad or too small. The roads are also fairly narrow with a lot of trees so it all depends how comfortable you are negotiating turns. We have a 40-footer and did fine, but we did squeeze a bit to get into our site. Someone else came in a 45-footer and did manage to get in after 40 min's of effort. So, it's possible to get big-rigs in here. The surrounding forest is thick and has wild raspberries in summer. It's pet-friendly and you can walk the dog in the forest, but there's no trails. Sites are reservable online. There are water spigots around the campground, but no dump-station (nearest dump is Sinclair gas station in Custer where you can dump for $4). We camped at Comanche Park in a Motorhome.
