Exploring Harmondsworth Moor
To the left of the Five Bells pub, follow Moor Lane as it curves and narrows before coming to a bridge. Turn right into the first part of the moor that this walk explores.
Take the right fork alongside the Duke of Northumberland’s River and keep ahead to reach a mound shaped like an amphitheatre that faces a group of large granite blocks. This is known as the Giant’s Teeth and the blocks belonged to old Waterloo Bridge, which was demolished in 1935.
Proceed counter-clockwise around the Giant’s Teeth, ignore the first stile on the right but go over the second to ascend the steps to reach a suntrap with two benches. Continue down the steps past the benches, go left along the path, exit through the gate and turn right. When the path divides take the right fork, go over a humped bridge and return to the gate you came in through.
Cross the road and go through a kissing gate (locked Monday–Friday 6am–10.30am) that gives access to the part of the moor including Swan Lake that is adjacent to the Waterside office complex. Turn right and follow this path beside the lake, then exit through a gate a little further on the right.
Cross the road and take the footpath alongside the car park, entering the larger part of the moor. Follow the path round to the left and cross over the River Colne via the bridge. (Ahead to your right is Half Moon Meadow, popular for picnics.) Turn left and keep ahead along the path, taking the left fork when the path divides, and keep going to cross the boardwalk over the ponds, ascend and go left over the footbridge.
Go through a kissing gate and turn right, passing a car park on the left. After 55–110yds (50–100m) turn right through a kissing gate on to a bridge (sign posted ‘The Keyhole’). Turn right and then take any left-hand fork uphill to reach The Keyhole, where you’ll see more stones from Waterloo Bridge. From here there’s a good view of the surrounding area and Terminal 5. Notice the words of Alfred, Lord Tennyson that are aptly carved in the blocks: ‘For words like nature half reveal and half conceal’.
Continue along the path and take the left fork leading to a kissing gate and a bridge back over the Wraysbury River. Turn left through the kissing gate. At a fenced T-junction turn right and follow the narrow path to a bridge over the northern part of the Duke of Northumberland’s River.
Cross the bridge and after a while turn right, signposted ‘Harmondsworth’, along a path that skirts the edge of Saxon Lake. At the far end, go through the kissing gate and right along a narrow track, at the end of which is a metal gate leading to the churchyard. At the other end of this is the Five Bells pub, where your walk began.
