Turn left, uphill, then descend towards the Tamar. Pass Clamoak, here entering the Cornwall and West Devon Mining Landscape World Heritage Site, then head upriver. Keep an eye out for a nice wooden installation, carved with representations of local wildlife: speckled wood butterfly, kingfisher, common sandpiper, little egret, grey heron, avocet and glow worm.
On the other side of the lane a track leads to the remains of South Tamar Mine, worked for silver and lead from medieval times. With the advent of steam pumping in the 19th century, mining extended under the river; in 1856, on a Sunday (so fortunately no lives were lost) the water burst into mine, stopping profitable extraction in its tracks.
Pass a limekiln on the right, then Weir Quay Boatyard, site of an 18th-century quay and, in the 19th century, the Tamar Smelting Works, servicing the South Hooe mines located on the peninsula just upriver. Pass a lane to Cotts (note the VR postbox on the corner).
Across a broad meander of the river look for Pentillie Castle (on the Cornish side), built in 1698 and largely rebuilt in 1810.
At Holes Hole note a house called the Basket Factory, denoting its former use; the quay here also served local mines. The house on the laneside is the former Tamar Hotel, hosting guests arriving by boat.
As the lane bears right and starts to climb out of the valley look out for a footpath on the left.
