Turn left along the wooded riverbank. The path passes a substantial lock and basin, part of an ambitious late-18th-century scheme to make the Tamar navigable as far as Launceston. Then, another canal would link Launceston with the north coast at Bude. The Bude Canal was achieved, but further south only this 3-mile (4.8km) stretch from Weir Head at Gunnislake, to Morwellham, was completed in 1801. The canal, which became known as the Tamar Manure Canal, although it also transported coal, sand, bricks, lime and granite – ceased operation in the 1920s.
The path passes canal workers’ cottages; immediately before a pair of cottages on the right, bear right on a narrow path. Continue upstream, passing the site of Bealswood Brickworks, opened in 1850 and the largest in Cornwall until closure in 1914. Pass the weir – a fish weir built by the monks of Tavistock Abbey, and rebuilt c. 1800 – at the tidal limit of the river. The riverbank here is private – it’s a beautiful spot. Follow the path on, close to the water again, passing beneath Chimney Rock and magnificent tree-covered river cliffs.
Look out for glimpses of six-arched New Bridge – which dates from the early 16th century, was the site of a Civil War battle in 1644, and was painted by J.M.W. Turner in 1814. The path gains the road at the west end.
