Tavistock Canal

Take a look downstream from Abbey Bridge. To the right of the weir you can see the head of the canal feeder channel; a mechanical scoop keeps the sluice gates clear of leaves and other debris. When barge traffic stopped the canal was used to supply water to mines along its route until 1930. In 1933 it was bought by West Devon Electric Supply Company to feed their hydro-electric power station at Morwellham, still operating today. Head towards the roundabout, then bear right down St John’s Avenue. Pass to the right of a car park then through Benson Meadow, named after a 19th-century benefactor (look out for St John’s Holy Well on the left).

Cross the Tavy on an iron bridge to enter The Meadows, former meadowland which became a park in 1898. Turn left; pass the children’s playground and take the next path right, to leave the park and pass under Plymouth Road. Turn right up steps, then right and left to meet the canal opposite Fitzford Cottages, built to house Bedford estate miners, farm and foundry workers in 1862.

Turn left along the narrow canal-side path. Pass Monksmead Swing Bridge; the path broadens as it runs through Crowndale Woods. Quarries on the far bank provided the stone used to build the canal; if the water is low you can sometimes see where the horse-drawn barges (one horse downstream, two horses back up) scarred the stone lining. The canal runs behind Crowndale Farm; Sir Francis Drake was born in a longhouse here in 1540. Follow the path under a pretty single-arched stone bridge, built to access Wheal Crowndale, which opened in 1799 and produced copper (note blue-green staining on the underside of the bridge) and arsenic, and some tin and iron. Pass an engraved wooden post bearing MM (Millennium), T (Tavistock) and G (Gulworthy), marking the parish boundary, as the canal curves right at Shillamill; the Rivey Tavy, far below, heads south to join the River Tamar. The canal continues to bear right, now running up the valley of the River Lumburn, and carried over the old road to Bere Alston (now an overgrown track) via an iron bridge. The magnificent Shillamill Viaduct was built in 1889 by the Plymouth, Devonport & South Western Junction Railway, one of four such structures between Plymouth and Tavistock (the line closed in 1968). Walk on to reach the only lock on the canal, complete with lock-keeper’s cottage, and a dock for tying up barges. Continue over the rock-built aqueduct, towering 60ft (18m) above the River Lumburn.

Reach the end of public access along the canal, marked by a wooden installation and poem by James Crowden: ‘End Game’. Here the canal bears left into private land, soon entering a 1½-mile (2.4km) long tunnel, cut deep through Morwell Down, to emerge high above Morwellham (the waters now diverted into a reservoir to feed the HEP station). A track heading away on the far bank is an old tramway, built over a canal spur intended to serve slate quarries at Mill Hill. There was never enough water (sourced from the Lumburn) to render it usable, and it was replaced by horse-drawn wheeled transport. Retrace your steps along the canal to pass under the Plymouth road and enter The Meadows

Take the first path left to pick up the canal again, and turn right alongside it. Pass Meadowlands Leisure Centre to reach the old canal wharf and the point where the canal emerges under the bridge on Canal Road (access to Bedford car park); an information board details the history of the canal and adjacent buildings. Continue on to the edge of the car park, then turn right to pass through the boundary wall and meet the River Tavy; turn left along the Abbey Walk. Pass the Abbey Still Tower (restored in 1884), where the monks distilled herbal medicines, using flora from their nearby gardens, on your way back to Abbey Bridge.
