About
Overview

Campsites are available for reservation for the Peak-Season times of May 1st through September 15th. All sites are first-come-first-serve from September 16th through April 30th.
Trapper Springs Campground is adjacent to the lower Madison River and provides good access for camping, fishing and floating. The campground has 15 camp sites, 9 available for reservations. There is no boat launch available at this site, but there are several in the vicinity. The campground serves as a great central location to access the lower Madison River.

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. Trapper Springs sits roughly half way between Warm Springs boat launch and Black's Ford Fishing Access Site.
Facilities
15 campsites, 3 accessible vault toilets, drinking water, group use pavilion, fire pits, and picnic tables. Firewood is available for purchase at Red Mountain Campground, when the volunteer campground host is present.
