The campground has a volunteer seasonal campground host. There is no boat launch available at this site, but there are several in the vicinity.

Recreation
The Madison River is well known for its robust trout fishery. The lower Madison River is a very popular destination for non-angling floaters (tubers) during the warm summer months. Red Mountain sits roughly half way between Warm Springs boat launch and Black's Ford Fishing Access Site.
