The main traffic on the Canal is the late 1800's was bricks made from the local clay.

Turn left at the junction onto the Grand Union Canal.
You will reach your first lock at Cowley Lock as you start the climb up the Colne Valley and the Chiltern Hills.

Cowley and Uxbridge to your right are the last of the outer suburban belt that surrounds London, and you will soon leave all that behind.

There is a large shopping centre in Uxbridge, access from Bridge 186.

The Battle of Britain was directed by the late Air Marshal Lord Dowding from the RAF HQ in Uxbridge.
The town has a selection of modern and futuristic buildings.

In the early 19th Century the Paddington Packet Boat used to run daily from Paddington to Cowley, pulled by 4 horses, it made the 15-mile lock-free journey in a remarkable time, taking passengers up and down the canal.

East of Bridge 80 there are shops at South Harefield.

Black Jack's lock and Copper Mill Lock are very attractive with tiny timbered cottages, a small mill, and attractive canal-side buildings.
The big mill at Copper Mill was once a paper mill, but when the Canal was built it re-invented itself and made copper sheets for the bottom of boats.
