The Oxford Canal runs from Hawkesbury Junction, where it connects with the Coventry Canal, to Oxford, where it connects with the River Thames – across its 120 km (75 mi) length, there are 46 locks.
The section between Braunston and Napton Junctions is generally considered to be part of the Grand Union Canal.
There is one branch, Duke’s Cut Branch, which runs for 1.3 km (0.8 mi), with one lock, from just below Duke’s Lock No 44 to the Thames.
It is often said to be one of Britain’s most scenic canals and is much used by pleasure craft; in fact, in the summer months, it is one of the busiest canals on Britain’s network. The stretch north of Napton-on-the-Hill in Warwickshire is part of the Warwickshire Canal Ring.
The Oxford Canal Walk is 132 km (82 mi), running the length of this canal’s towpath with an additional 9 km (5.5 mi) extension along the Coventry Canal from Hawkesbury Junction to Coventry. This walk is very popular for geocaching.
