Locks, bridges, wharves, junctions and other features of the canal network, from Canal & River Trust open data. They’re useful as landmarks when planning a trip or finding a listing.
A scheduled ancient monument and one of the great feats of British canal engineering: 29 locks in all, including a continuous flight of 16 locks rising 237ft over two miles at a 1-in-44 gradient. Free towpath access, a CRT car park and café make it one of the most-visited sights on the whole canal network.
Braunston is one of the great meeting points of the English canal network, where the Grand Union Canal’s main line joins the Oxford Canal. This stretch is known as the Braunston Summit, and it feeds the lock flights at both Braunston and Long Buckby, drawing water from Drayton and Daventry reservoirs. The village sits a couple of minutes’ walk up the hill from the junction and has a pub and cafe, while down on the water there’s a volunteer-staffed information point at the historic Stop House, plus Braunston Marina nearby offering moorings and boatyard services. The towpath is open every day, and it’s a popular spot for boaters to pause, whichever direction they’re heading.
Hanwell Lock Flight is a striking flight of seven locks on the Grand Union Canal at Hanwell, in the middle of London, where the canal drops down to meet the valley of the River Brent. Despite its urban surroundings, the flight has a surprisingly rural, wooded feel, and it’s a popular spot for a towpath walk. Along the flight you can still see historic features from the canal’s working days, including lock keeper’s cottages and a horse ramp built to help tow-horses that fell into the water climb back out. The towpath is open and free to explore year-round. Hanwell railway station is about a 15-minute walk away, and bus route B3 also serves the area. Visitor moorings are available at both ends of the flight, with further facilities nearby at Bulls Bridge.
