SK1871 : Monsal Dale
taken 47 years ago, near to Monsal Head, Derbyshire, England
The Monsal Trail is a traffic free route for walkers, cyclists, horse riders and wheelchair users through some of the Peak District's most spectacular limestone dales.
The trail runs along the former Midland Railway line ( Link ), which closed in 1968, for 8.5 miles between Blackwell Mill SK1172 : The start of The Monsal Trail, in Chee Dale and Coombs Road, at Bakewell.
Most of the route was opened to the public in 1981 but four former railway tunnels had to remain closed due to safety reasons, with public footpaths taking people around them. In 2011 the four railway tunnels - Headstone Tunnel, Cressbrook Tunnel, Litton Tunnel, Chee Tor Tunnel were opened for trail users. Each tunnel is about 400 metres long and will be lit during normal daylight hours.
