Cyclists, walkers and horse riders out to enjoy the Monsal Trail this winter are being urged to check the tunnels website before setting out.
The Peak District National Park Authority, which owns and manages the Monsal Trail, may have to close the tunnels at very short notice over the winter for safety reasons.
They are being monitored daily and checked for ice, icicles and any maintenance issues that the cold, wet weather may cause.
If the tunnel conditions become unsafe due to the bad weather, the website will be updated and signs will be placed on the trail at Bakewell station, Hassop station, Great Longstone station, Millers Dale station and at Wyedale and the gates will be locked.
The website to check for up to date information on the tunnels is www.peakdistrict.gov.uk/monsaltrail
