Maiden Castle, Roslin Glen
10th February 2023
A short meandering walk exploring a varied section of the River North Esk at Roslin Glen and Bilston Glen.
THE ROCKS: This area is an important part of the Midlothian coal basin, with sandstone, limestone and mudstone layers visible in the river valleys. These layers have been eroded by glacial meltwater as the ice melted at the end of the last glacial period, creating an impressive gorge whose sides are still unstable, as demonstrated by the Hewan Bank landslide.
THE WALK: from Loanhead we will follow good paths and tracks (which may be muddy in places) into Roslin Glen, inspect the landslide from Springfield Mill, and return to Loanhead via Bilston Glen. Total distance 6.5 km. I have classified this as a Moderate walk: not always on paths, it may be rough or slippery underfoot at times. It may be wet, windy or cold. Come equipped with strong footwear and waterproof clothing.
