We chose Swan Creek from the few USFS campgrounds between Big Sky and Bozeman based on how far it was off of Rt. 191. The others are located right along the road, yet next to the Gallatin River. We heard no road noise and had the soothing sound of Swan Creek in the evenings. But, don’t expect any cell service from any of these USFS campgrounds in that area. If you’re okay with that, this was a great place to setup camp to checkout the area. Lots of great hiking.
