Brentford Gauging Lock was once one of the busiest places on the Grand Union Canal / River Brent. Today, Brentford Lock is a great place for a walk and cycle.
Just a 10 minute jaunt around the towpath is the Thames Lock the final lock on the Grand Union Canal and the gateway to the River Thames. Or if your prefer the 15 minute walk the other way, you'll find Syon House and Park.
