It's really lush along there at the moment as the trees and bushes are all in full leaf. The paths and woodland areas are well maintained by a sterling group of volunteers (see above link) and are accessed at many points from the adjoining roads by stairs made form old railway sleepers. There are also information points along the way explaining the various flora and fauna to be found there.
Parkland Walk is frequented by joggers, dog walkers and people just out for a stroll enjoying the greenery. And, just like London's canal paths (well, apart from the Camden stretch of the Regent's Canal), this walk makes you feel as you have left the concrete city when really it is only just a few metres above or below you.
The pictures below are all from the stretch between Finsbury Park and Crouch Hill. More posts and pictures about this thin stretch of nature to follow.
