A river port from medieval times, exporting tin and wool from Tavistock Abbey, Morwellham grew in size under the ownership of the Dukes of Bedford. In 1817 the Tavistock Canal was completed, and connected to the port by an inclined railway, powered by a waterwheel. The DGC railway incline, built in 1858, saw an increase in the amount of ore passing through the port, leading to the building of new quays. In the mid-19th century some 500 vessels landed here each year. Retrace your steps to Point 4. Bear left, rounding a wooden barrier. This pretty track heads down the combe, passing a fenced-off mineshaft, and soon runs high above the stream. As the valley edge is reached the track curves right, uphill, and peters out; here bear left on a narrower valley-edge path. This wonderful little path winds through the trees, passing above a run of rocky crags – it’s rough, with a very steep drop on the left, so watch your step. Pass a short fenced-off section above workings at Wheal Russell, and continue through the trees to reach the amazing fenced-off pinnacle of Chimney Rock, named after its resemblance to a mine stack. The path heads on through the pine trees – a little easier underfoot now – to reach a crossing track (South Bedford car park is signed to the left).
