We stayed here while attending the 3-day, Run the Rut trail races up at Big Sky at the end of August 2018. It was a 45-minute drive but we booked late and everything else was full. We really like this location, about 3 miles up Storm Castle Creek on a dirt road. It's a small, clean and quiet campground with sites not too close together. No road noise aside from a rare vehicle in the canyon and dust wasn't an issue. Two trailheads were along the dirt road. We explored Storm Castle, a short, very steep climb up but well worth the views. Very clean vault toilets and food lockers but nearest showers are in Bozeman. Bring buckets and warm stream water for washing... it's FREEZING cold! I tried washing my hair in the stream and it was painful. No showers available in Big Sky either. We stayed in site #10, close (but not too close) to the restroom. Nighttime temperatures were just above freezing and there had been rain the day before we got there so things were a little damp but no mud. The morning sun did shine down into the campground fairly early to warm things up.
