Canal Walks with Julia Bradbury

Julia starts this walk in the beautiful world heritage city of Bath, where the Kennet and Avon Canal provided a 19th century 'canal superhighway' between the country's two most important ports, Bristol and London. But only forty years later the trade along the canal was usurped by rail travel, leaving the once great waterway neglected and derelict. Julia's 20-mile walk, along what is arguably the most picturesque stretch of the canal, tells the story of how the waterway was restored to its former glory after it was awarded the biggest ever lottery heritage grant. The walk ends at the spectacular Caen Hill flight of locks, listed as one of the seven wonders of British waterways.

Julia's final walk takes her to North Wales, where two hundred years ago the great engineer Thomas Telford had to overcome seemingly impossible challenges in order to access the valuable slate industries of Snowdonia. In doing so he created a masterpiece of 19th century engineering - an aqueduct 126ft high and spanning a 1,000ft across the vale of Llangollen. To find out why it has become a world heritage site, Julia follows the cut of the Llangollen Canal, starting at the picturesque Horseshoe falls. Her six-mile walk takes her along the winding Dee valley, ending on the aqueduct that Telford described as 'a stream through the skies'.
