The Monsal Trail tunnels offer one of the most spectacular leisure routes in Britain for cycling, walking and horse riding.
It is the first time the public have been able to go through the tunnels since the former Midland Railway Line closed in 1968. Four of the longer tunnels are lit during daylight hours, dawn to dusk, to make them safe to use. They are operated by a light sensor, so in winter when the hours of daylight are less, the lights in the tunnels will switch off earlier in the day – around 4.30pm. If you are using the trail in the afternoon you are advised to take a torch or have bike lights in case you get caught out. If the lights go off because of a power failure there is a two hour emergency back up in place.
