TTFs on TrailBridge, Drop, Rock Face
A long lost trail that was recovered by the Great Falls Bicycle Club that is best ridden counter-clockwise. The first half is open prairie and has a few punchy climbs. The second half is the real fun filled with rock features, drops, and bridges.
Access Info
Start at the South Shore trailhead, ride down to Whitmore Ravine, then up red rock hill. At the top of hill go straight or go left, either way, keep heading east. After Ryan Dam, you will come to a fork in the trail. This is the beginning and end of Lost Fork Loop. Take the trail to the right up the hill and 1.5 miles later either stop at Box Elder Creek for a break or jump right into the technical section by taking the trail that turns towards the river.
