Sheep Mountain Professional Review and Guide
"This is the definitive Missoula ride, traveling the ridgelines high above two valleys to the highest peaks in the Rattlesnake National Recreation Area and then dropping down through mixed terrain of conifer forests and beargrass to the main stem of the Rattlesnake Trail System just north of Franklin Bridge. Because of the remote country the path traverses, the length of the trail, and the overall difficulty of this ride, only the strongest riders will want to tackle the course I describe here in one day.
A logging road through Plum Creek Timber Company land on the Highway 200 corridor at Gold Creek provides additional access—check with any of the local bike shops or riding organizations for details—but for those looking to bag a peak from the valley floor, there is no better way to go than the way I’ve laid things out here. Along the way, keep your eyes open for mountain lions, black and possibly grizzly bears, elk, deer, and more. Tread: Singletrack, doubletrack, and jeep and gravel roads."
