The Sheridan/Big Horn Mountains KOA sits along Big Goose Creek just off Interstate 90, operating from April through October as a base camp for exploring the Bighorn Mountains region. This private campground accommodates RVs up to 70 feet with full hookups across approximately 60 sites, plus 25 tent sites and 10 cabins. Each tent site includes its own covered picnic shelter, a feature that proved valuable during rainy weather according to multiple campers.
The campground maintains grass throughout its sites rather than the gravel surfaces common at many KOAs. Joel R. notes "This is, finally, a KOA that isn't covered in gravel and dust! There is real, green grass!" Sites run smaller and closer together than some prefer, though reviewers consistently praise the cleanliness of facilities. The modern bathhouse features separate toilet and shower stalls with locking doors and curtains that keep belongings dry.
Big Goose Creek flows alongside the property, offering fishing opportunities primarily for carp. An outdoor pool and spa operate during warmer months, along with a small playground, mini-golf course, and game room. The campground includes a dog park plus an additional unfenced area for dogs to run. WiFi works adequately for basic web browsing but struggles with streaming services. A small store provides basic supplies on-site.
Location brings both advantages and drawbacks. The campground provides easy access to historic downtown Sheridan and serves as a convenient overnight stop on I-90. However, proximity to both the highway and railroad tracks creates noise that some campers find disruptive at night. Staff consistently receive praise for their friendliness and local knowledge, often helping campers secure preferred sites with full hookups when available.
Campers seeking quieter alternatives might consider Peter Ds RV Park, located southeast of the KOA with less highway noise.
