Pleasant, not spectacular
The most important thing to know is that you will get lost, or at least confused, if you use the information listed on even the official website. This campground is NOT in the Caribou-Targhee NF, it is in the Cache NF. And the road is not marked as St.Charles Canyon Road; it is labeled as Minnetonka Cave Road. We wasted an unnecessary amount of time finding the campground because of this misinformation. We also had to wait for cattle that graze the area to move off the road.
This is a pleasant enough campground, with views of rock formations, a flowing creek, and plenty of wildflowers. There is good drinking water available, and the vault toilets were clean.
