Last Known StatusOpen

Home of the Annual Idaho City 100 and located about one hour north of the state capitol, this part of the Boise National Forest offers over 400,000 acres of premier woods riding with hundreds of miles of designated single track trails.

This trail sytem has multiple trailheads and several primitive campgrounds to choose from, but if you are looking for RV hookups or cabin rentals with direct trail access check out nearby Trudy's Kitchen.

This place is huge and will require staying several days to explore.
