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.

Walking
Location : Harrow
Starting point : N 51.568394° / W 0.339538° (D/A) The route starts near the top of Harrow Hill at the junction of London Road and Roxeth Hill.
Walk downhill: Roxeth Hill becomes Sudbury Hill.
(1) Turn right when you get to South Hill Avenue. Just across to your left here is a signposted bridle path officially know as Green Lane but known to locals as 'Piggy Lane'. This is an ancient wooded track which you follow to Sudbury Hill.
(2) At the bottom of the road turn left and walk along South Vale to join Greenford Road. Cross the railway line to your right. Turn left into Rosebank Avenue. You are now sandwiched between two railway lines. Follow Rosebank Avenue and then Maybank Avenue until you reach Harrow Road.
(3) Cross the road into Elms Lane and keep left.
(4) Look out for the entrance to Elmwood Park on your left. It is a fairly steep climb to the top of the park but well worth it for the views from the summit. The park is small, and is known locally as 'The Pimple'! Exit the park onto Sudbury Court Drive. Turn right along Sudbury Court Drive, crossing this busy dual carriageway when you can.
(5) Turn left into Mulgrave Road. This will take you on to Pebworth Road, where the signposted entrance to the bridle path back up to Harrow Hill is just ahead of you. A steep climb up Football Lane takes you on to Peterborough Road, where you go left for rejoining your starting point.(D/A)

Shops and cafes at Sudbury Hill and Harrow Hill High Street. You could also make the walk longer by diverting through Maybank Open Space (see map) to Sudbury and Harrow Road where there are shops including a Wenzels Bakery and cafes, plus access to Barham Park with its lovely walled garden. For anyone who is not familiar with the area, there are cafes and restaurants on Harrow Hill High Street and you could spend some time at the beginning or end of the walk exploring the environs of Harrow School. That could easily be a walk in itself, and one where you would be joined by many other walkers, particularly at weekends.

Starting point in Harrow - Greater London 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.

Starting point in Hertfordshire 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.
