Cromford Canal
The Cromford Canal ran 14.5 miles (23 km) from the the Great Northern Basin on the Erewash Canal near Langley Mill to Cromford just south of Matlock. It had four tunnels and 14 locks. It was used to bring in coal to the increasingly industrialised Cromford area whilst limestone, lead and cotton were transported away. One mile south of Cromford lies High Peak Junction where the Cromford and High Peak Railway came down an inclined plane to meet the canal. This railway carried coal and limestone between High Peak Junction and the Peak Forest canal at Whaley Bridge. A 6-mile (9.7 km) long section of the Cromford canal between Cromford and Ambergate follows the 300-ft contour and is in water, although navigation is not possible due to its isolation. This Site of Special Scientific Interest is popular with walkers.
