The Pymmes Brook Trail is located in the London Boroughs of Barnet, Enfield and Haringey and is just under 13 miles (21 km) long. The brook is named after William Pymme, a local landowner.
The trail goes from Hadley Green to Tottenham Hale, where the trail connects with the Lea Valley Walk. Most of the first half of the trail, as far as Arnos Park, runs beside Pymmes Brook, but after that the brook is only encountered intermittently as much of the brook passes through private land which is not open to the public. In its lower reaches sections of the brook have been culverted to alleviate the risk of flooding.[1]
