Potosi Campground and Picnic Area
This is a nice campground located on the east side of the Tobacco Root Mountains with South Willow Creek running through the middle. There are 15 designated campsites, a picnic day-use area, vault toilets, and drinking water at this site. There are no garbage services, so pack it in and pack it out. We recommend trailer length does not exceed 22’.
