This is the forth cache in a series leading DT to a birthday surprise along The Great Northern Railway Trail.
The trail follows a disused railway line that originally ran between Cullingworth and Queensbury connecting mill towns in the area. It became known as Alpine Valley because of its stunning scenery and sequence of tunnels and viaducts winding through the valley.
This is a small magnetic cache. Please bring your own pencil and tweezers along.
