Rock Pile Mountain Wilderness Area Trail

From the trailhead there is a 2 mile section of maintained trail. The rest of the wilderness area is accessed by old woods roads or cross-country hiking.

The 4,131-acre Rock Pile Wilderness takes its name from an ancient circle of granite rock, piled by some earlier man on top of the mountain. It is located in Madison County on the Fredericktown Ranger District, southeast of Bell Mountain and southwest of Fredericktown, Missouri. The area is primarily a broken ridge, having steep rocky slopes running from Little Grass Mountain on the north to the National Forest boundary four miles to the south.

Rockpile Mountain itself, the steep limestone bluffs, rock formations, and caves along the St. Francis River. The narrow gorges or "shut-ins" with rushing cascades during periods of runoff and the scattered granite glades add variety to the wilderness landscape, as well as unique plant and animal communities.
