Knoxville Recreation Area

Wednesday, January 31, 2024

Other Names

Rocksville, Hunting Creek Camp, Jericho Creek, Morgan Valley Road, Devilhead Road

Last Known StatusOpen

This large area of public land offers 51 miles of rugged 4x4 roads and some single track motorcycle trails. There are two entrances to this area, Hunting Creek Camp (Lower Camp) and the Northern Staging Area (Upper Camp). The Upper Camp is dry and rocky, (bear right at the fork!) and offers only two campsites, both primitive. Upper Camp is accessible by large vehicles and trailers but there is no room to camp or park.

While the Upper Camp does have more trails, Lower Camp offers more room for RVs and trailers, but the road is steep and rocky. This camp has five developed sites with tables, fire rings and direct access to the creek. Look for an opening in at the back of the campground to find a motorcycle trail that follows the creek and leads to two great swimming holes (first hole is 1/4 mile in, waterfall is 1/4 mile past that).

You can ride from the Lower Camp to the Upper Camp by following the main access road right through the campground, across the curved bridge and up over the ridge (make no turns). Follow the road about 7 miles to the Upper Camp area.

Many locals playfully call this place "Rocksville" because of the many rocks, but we've seen bigger chunk. As long as you use a skid and guards you'll have no problems.

This waterfall makes for a nice refreshing dip after a long day of riding. To get to this swimming hole take the single track motorcycle trail from Hunting Creek camp for about a half mile.
