Distance and timing basis
Ordered leg totals agree within rounding. Stop distances are approximate sums of rounded legs. Stops, delays, approach and any separate return travel add time. Basis: producer-declared routed record.
Reading history stays on this device. My road watch requires a separate selection; opening it does not subscribe this ride.
Distance and riding time are measured on the routed road. Check local closures and conditions before you ride.
An 81 km round trip from Saint Agnes - roughly 1 h 44 in the saddle. On the way it passes Kennall Vale, Tregonning and Gwinear Mining Districts and back through Kennall Vale. It was put together for the scenery rather than the shortest line.
Waypoint introductions and full write-ups
1. St Agnes Mining District
St Agnes is a village of fewer than three thousand people on the north coast of Cornwall, and its coastline is one of the most photographed in the county. The reason is Wheal Coates, a pair of engine houses perched on a cliff above the sea at Chapel Porth, the sort of view that appears on tea towels. The engine houses once pumped water from tin and copper mines that ran under the cliff, and miners worked in tunnels that went out beneath the waves. Today they stand roofless, with ferns in the windows, against a sky that seems to change every few minutes.

Planning note
St Agnes Mining District is where the day begins. Next is Kennall Vale.
2. Kennall Vale
Kennall Vale is a steep, wooded ravine in the middle of Cornwall's mining country, and for a hundred years its stream was used to make gunpowder. The mills, built in the early nineteenth century, produced the powder that miners used to blast tunnels and shafts in the tin and copper mines, and the valley was chosen because it had water, privacy and trees to absorb explosions. The gunpowder works closed in the early twentieth century, and the buildings fell into ruin. Now the old mill walls stand in a thick green wood of oak, beech and ash, with moss on every stone and a leat, the stone-lined channel that brought the water, still threading through. It is one of the most atmospheric places in west Cornwall, and a nature reserve.

Planning note
Kennall Vale comes up about 18 km into the recorded legs. Next is Tregonning and Gwinear Mining Districts.
3. Tregonning and Gwinear Mining Districts
Tregonning Hill is a low, rounded granite dome above Germoe, and on its slopes in the middle of the eighteenth century a Plymouth chemist named William Cookworthy found white clay of a quality that Europe had never produced. He recognised it as kaolin, the secret of Chinese porcelain, and the find began an industry that eventually shifted to the larger deposits around St Austell. The ground around Tregonning and Gwinear is a landscape of old tin and copper workings, engine houses, abandoned stacks and small fields enclosed by stone hedges. The whole Cornish mining landscape was listed by UNESCO in 2006 and these districts are part of it.
