Parkland Walk Local Nature Reserve

The Parkland Walk is a 3.1-mile linear green pedestrian and cycle route in London, which follows the course of the railway line that used to run between Finsbury Park and Alexandra Palace, through Stroud Green, Crouch End, Highgate and Muswell Hill. It is often mistakenly described as 4.5 miles long, but even taking in the gap between the two sections it still only totals 3.1 miles. The route follows the bridges and cuttings of the line, but avoids the closed surface section of Highgate station and its adjoining tunnels, which are closed to walkers for safety reasons. The walk is almost all in Haringey, but a short stretch between Crouch Hill and Crouch End Hill is in Islington and this section incorporates Crouch Hill Park.

The walk is a local nature reserve and a Site of Metropolitan Importance for Nature Conservation. It was declared a local nature reserve in 1990 and is London's longest such reserve.
