There are lots of walking route option across Scotland, from costal routes to woodland trails. But one specific route may spark the interest of fans of a more eerie afternoon stroll.
Just south of Perth you will find the Glenfarg Railway Tunnels, one north and one south. Not a route for the claustrophobes out there, the tunnels are both around 500m long and are pretty dark and dreich.
The north tunnel is the more curved of the two, meaning darkness is more absolute for a while, while the south route is a little straighter to allow for the tiniest beam of light to shine through from the other end.
So it is best to make sure a decent torch - or head torch - is on hand, no matter the time of day or weather.
The unusual route provides walkers will a little bit of mystery of their trek, with the route a little difficult to negotiate at times.
The tunnels possess original features, including inspection holes and stone work.
The tunnels made up part of the North British Railway line, which opened way back in 1890 on the same year as the Forth Road Bridge. The line provided a direct line from Edinburgh to Perth, with the Glenfarg stretch notoriously steep.
However, the line was closed in 1970 to allow the track bed to be used during construction of what is now the M90.
How to find the Glenfarg Railway Tunnels
Walkers can opt to take on either the south of north tunnel first, the route can be tackled in either direction.
The route an be accessed through a gate on south-west side of the B996.
Alternatively, the walk can begin from the Bein Inn Hotel at the junction of the A912/B996 or from laybys on route. Customer parking restrictions may apply.
From the hotel, walkers should head north for around 200m along the A912. When reaching a farm track opposite a road sign for "Binn Eco Park".
Follow the track to find the railway bridge before walking towards a wooden gate on the right hand side to join the route of the railway line towards the tunnels.
