Northwood HQ 21KM

This is the first section of a 12 mile walking route which follows the River Pinn from Pinner to Uxbridge. Of all Middlesex's 'lost rivers' the River Pinn is perhaps the most visible.

This beautiful walk takes you from the outskirts of Watford into the depths of the countryside to see a host of wild flowers.

This walk gives you the opportunity to experience the abundance of wildlife in the beautiful Colne Valley across many different types of habitat. It’s a wonderful location for all ages to explore and enjoy with the possibility of spotting rare migrating birds.

This walk starts at Ricky Aquadrome with its 3 lakes and goes along a delightful stretch of the River Chess, through Whippendell Woods (particularly nice in mid April when the bluebells are out), to Cassiobury Park with its 2 cafes and voted one of the 10 best parks in Britain and along short stretches of the River Gade and Grand Union Canal. Do allow plenty of time for exploring the many interesting features on this walk.

This walk visits Rickmansworth and Croxley Green, whose current size and character owe much to the arrival of the Metropolitan Railway. The varied route includes woodland, fields, a moor designated as a Site of Special Scientific Interest, a village green, rivers and a canal.

This is a short urban walk exploring another of the 'lost landscapes of Middlesex'. The Yeading Brook rises at Headstone Manor and can be tracked all the way to Ruislip Gardens. This walk starts and finishes in West Harrow, and follows the most attractive section of the river through two pretty linear parks : The Yeading Brook Open Space and Streamside Recreation Ground.

The Wealdstone Brook is one of the lost rivers of Middlesex. It's a short urban walk, one of my 'lost landscapes' routes around the Harrow area. Ironically, there is no trace of the river left in Wealdstone itself, where it has all been culverted. However, it meanders very prettily through Woodcock Park in Kenton, surrounded by grassy banks and willow trees. This is the best bit! There are further glimpses of it along the route of this walk.

This is a short urban walk exploring the 'lost landscapes of Middlesex'. I was recently introduced to a secret park which I never knew about, and realised this must be the summit of the original Sudbury Hill before it was swallowed up under the tide of suburban housing. The walk visits Elm Park and also takes you past the Harrow School sports fields. It starts and finishes near Harrow School, Harrow-on-the-Hill.
