The Pymmes Brook Trail is located in the London Boroughs of Barnet, Enfield and Haringey and is just under 13 miles (21 km) long.
[1] The trail starts on Hadley Green, where the headwaters of Pymmes Brook rise, with a link from High Barnet tube station.
Together with the London Loop, it then drops through Monken Hadley Common to Jack's Lake, to meet another link from Cockfosters tube station.
The trail recrosses the North Circular Road onto Silver Street, Edmonton, where the path enters the gardens of Millfield House.
As of 2018, the trail must temporarily follow public throughfares for a short distance, but will eventually take a new route when access to the brook is opened up in the Meridian Water development.
