Rockpile Mountain Trail

The trail is located in the Rockpile Mountain Wilderness Area, from the trailhead there is a 2 mile section of maintained trail. The rest of the area is accessed by old woods roads or cross-country hiking.

The trail begins on the summit of Grassy Mountain, and from there descends from 960 to 520 feet above sea level as the path clings along the slopes and descends into the hollow below. The trail shepherds hikers along for two miles of uneven terrain before fading into the rugged landscape. Then the trail divides multiple times to follow abandoned logging and mine roads that access the rest of the area. The maze of trails requires good orienteering skills.

Signage is infrequent, and the trailhead is sheltered from the slope by growth of trees. A large boulder carved with the words “Rock Pile Wilderness” marks the beginning of the trail. The road up Little Grassy Mountain to the trailhead is steep, and frequently washed out.

Rating: Moderate. Terrain is sometimes steep. The area is within the St. Francois Mountains where elevations range from 1,305 to 520 feet.

Length: 2 miles.

Best Seasons: Fall, winter, and spring.

Surface Type: Unsurfaced, native material.

This 4,238 acre Wilderness takes its name from an ancient circle of granite rock, piled by some earlier man on top of the mountain.
