River Pinn


The River Pinn is in the historic county of Middlesex, in the western part of Greater London. Its source is in Harrow Weald and its confluence with Frays River forms a tributary of the River Colne.

Route

The River Pinn runs through Pinner, Eastcote and Ruislip: the latter derives its name from "Rush leap" - this being a reference to the width of the river in the area. It then runs through Ickenham and on to Uxbridge, where it passes through the former grounds of RAF Uxbridge and Brunel University. The Pinn continues on to Cowley where it joins the Frays River at Yiewsley.
During the Second World War, the river was temporarily dammed near Pinner High Street for use as a water supply for putting out fires from air raids.

Celandine Route

Celandine Route is a 12-mile walk through an area of woodland, meadows and parks. It finishes where the River Pinn meets the Grand Union Canal. A short walk down the "Slough arm" of the Grand Union Canal brings one to Fray's River.
