The Parkland Walk[a] is a linear park along an abandoned railway line that used to go from Finsbury Park through Stroud Green, Crouch End, Highgate and Muswell Hill to Alexandra Palace. The railway saw less and less use from 1954 until it was closed in 1970. Tracks were removed and buildings demolished, and the Parkland Walk opened in 1984.
The Parkland Walk goes across the bridge seen in the picture. The stairs in the next photo begin just to the right of the white sign that can be seen among the leaves on the right side of the sidewalk.
The Parkland Walk. This is what you see about thirty seconds away from the stairs. It's like being teleported to a different place.
