Slipway at Harefield Marina on the Grand Union Canal for narrowboats between 30ft and 67ft, with a covered wet dock, hull blacking and anode fitting.
A covered, heated dry dock and slipway at Circus Field Basin, on the Aylesbury Arm of the Grand Union Canal, between locks 14 and 15. An electric winch brings the boat out of the water, then lifts raise it about 2ft 4in, giving access to the whole base plate for blacking, surveys and hull work. Dirty and clean workshops, a kitchen, showers, toilets and a laundry are next to the dock.
Home to two steam beam engines dating from 1812 and 1846 that pump water 40ft uphill from Wilton Water reservoir to feed the Kennet & Avon Canal’s summit level — among the oldest working beam engines in the world. Run by the Kennet & Avon Canal Trust, with open days through the season when the engines can be seen working under steam.
Built in 1810 by John Rennie to carry the Kennet & Avon Canal over the River Avon at Brassknocker Basin near Bath. In 1951 it became the first canal structure ever designated a Scheduled Ancient Monument. Visitor moorings, a café and cycle hire are available nearby at Brassknocker Basin.
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.
