About This Trail

Imported description

It is off the North Fork road. It should start at Y as the road is poor beyond Y. It was an easy grade as it was a road into the park. It needs some trail maintenance. As you approach the Crystal Cave road, you become "Upper Colony Mill". The trail goes around the ridge. It's a good view of how far you walked.
