The Kennet & Avon Canal stands as a testament to Georgian engineering and modern-day restoration, offering a picturesque journey through the heart of Southern England. Connecting the River Thames in Reading to the River Avon in Bristol, it forms a vital inland navigation route and a cherished heritage asset.

• Chief Engineer: John Rennie the Elder

The Story of its Construction

The vision for the Kennet & Avon Canal emerged in the late 18th century, driven by the desire to create a continuous inland water route between London and Bristol, bypassing the treacherous sea journey around the south-west coast. The project was primarily the brainchild of private companies, with significant backing from local landowners and merchants keen to facilitate trade.

Construction began in 1794, with the renowned Scottish civil engineer John Rennie the Elder at the helm. The ambitious project faced immense engineering challenges. The terrain across the Pewsey Vale presented significant elevation changes, requiring an ingenious system of locks and a reliable water supply. The infamous Caen Hill Locks at Devizes, a flight of 29 locks, was one of the greatest obstacles, requiring massive excavations and the movement of vast quantities of earth. Furthermore, maintaining sufficient water levels over the summit pound (the highest section) was critical, leading to the construction of innovative solutions like the Crofton Pumping Station.

Despite financial difficulties and the sheer scale of the undertaking, the canal was finally completed and opened in 1810. It quickly became a bustling commercial artery, transporting coal, stone, agricultural produce, and manufactured goods.

Key Features and What Makes This Canal Special

The Kennet & Avon Canal is celebrated for its remarkable engineering and the diverse, beautiful landscapes it traverses. It is perhaps best known for the dramatic Caen Hill Locks near Devizes, often considered one of the wonders of the British canal system. This spectacular flight of 29 locks, set in a rural landscape, is a marvel to behold and navigate.

Other notable structures include the elegant Dundas and Avoncliff Aqueducts, which carry the canal high above the River Avon. The Crofton Pumping Station, near Great Bedwyn, houses two magnificent beam engines, one of which is the oldest operating steam engine in the world still performing its original function – pumping water into the canal’s summit pound. The canal also passes through parts of Bath, a UNESCO World Heritage City, adding to its unique charm and historical significance.

What It’s Like Today for Visitors and Boaters

Following a period of decline and dereliction in the mid-20th century, a monumental restoration effort, largely driven by volunteers, saw the canal reopened in 1990. Today, the Kennet & Avon Canal is a thriving leisure waterway, managed by the Canal & River Trust.

It is immensely popular with boaters, offering a leisurely cruise through picturesque countryside, charming villages, and historic towns like Bradford-on-Avon, Newbury, and Hungerford. Visitors can enjoy watching narrowboats navigate the locks, or simply relax by the waterside. The canal’s towpath provides an excellent route for walkers, cyclists, and nature enthusiasts, boasting a rich array of wildlife, including kingfishers, otters, and diverse bird species. Numerous pubs and cafes along its length offer welcome refreshment, making it a perfect destination for a day trip or an extended holiday.

Cycling and Walking the Kennet & Avon Canal

The towpath of the Kennet & Avon Canal is an incredibly popular route for both walkers and cyclists. Much of its 87-mile length is accessible, offering a mix of surfaces from well-paved sections, particularly around towns like Bath and Devizes, to more rustic gravel or earth paths in rural stretches. National Cycle Network Route 4 (NCN4) follows significant portions of the canal, providing excellent signposting. Key sections to explore include the dramatic Caen Hill Locks and the beautiful stretch between Bath and Bradford-on-Avon. While largely navigable on foot or by bike for its entire length, some more remote sections may require suitable footwear or hybrid bikes.
