Greentrees Crazy Woman Campground sits in the middle of Gillette, Wyoming, backed up against a hospital parking garage on one side and a main road on the other. The urban setting is immediately apparent, and tent campers should know the hospital's lights are intense enough to read by at night, though RV campers report the glow is less of an issue inside a rig. Spaces are small and tight, and some sites appear to house long-term residents year-round.
That said, reviewers consistently flag the facilities as clean, and the campground includes full hookups for RVs up to 60 feet, a dump station, WiFi, hot showers, and laundry. Nicole B. notes the "bathroom facilities were clean," and multiple campers mention the staff as flexible and accommodating, including for late arrivals. Shaded sites are available; site C5 is noted as level and well-shaded.
A few practical details worth knowing before arrival: the campground is cash only and does not accept credit or debit cards. Tent campers at sites near the parking garage have reported ant activity on the ground. Noise levels at night have run quieter than the location might suggest, though the lighting situation is a consistent trade-off. Campers looking at campsites near Gillette will find this one among the most full-service in the area. It makes the most sense for RV travelers needing hookups or an overnight stop with access to town amenities.
