The Penicuik - Dalkeith Walkway, situated in the county of Midlothian in the east of Scotland, stretches for 9.5 miles along the former Edinburgh to Peebles railway.
The gentle gradient and nature of the route allow easy access for walkers, cyclists and horse riders to explore and enjoy the spectacular landscapes and visitor attractions of the county.
This section followed the trackbed of the old Waverley Line, which forms part of the Borders Railway which opened in September 2015.
Following the closure of the railway in 1967, nature has created an intricate wildlife corridor with a diverse range of habitats.
At one time polluted by Midlothian's industrial past, the river now is home to a rich variety of wildlife, including the shy otter and the exotic-looking kingfisher.
