Prospect Shafts is a steep route down Mt Helena. The route starts below the summit at an intersection with Backside
Very loose and rocky at first, the trail is wide and runs down an open face. The grade eventually lessens and the trail becomes more narrow as it traverses towards the Mt Helena trailhead.
Be aware of other trail users, especially runners and hikers. Prospect Shafts is one finishing option for the Mt Helena Ridge ride.
