Parkland Walk is an absolute gem of a local resource for Londoners. It follows the route of the former railway that linked Finsbury Park to Highgate and is now a green walkway just under three miles in length. It can be accessed from a number of locations along its length and during our walk, it was popular with runners, dog walkers and families out for a jaunt. The website
https://www.parkland-walk.org.uk/ has many details about the walk and the history of its development.
