Tips from the Community
Awful for cycling - loose gravelly steep uphill and downhill. Had to get off bike and push

Built in 1897, this calciner was used to roast arsenic ore - check out the date above the archway. Arsenic gas was driven off by the heat and travelled towards the stack higher up the hill and through the labyrinth, or lambreth, where it condensed on the walls. See this link for a diagram of the Brunton roasting furnace with the revolving hearth upload.wikimedia.org/wikipedia/commons/a/af/Brunton_roasting_furnace.png

Worth climb to the cairn for the downhill section on the main access road. Then drop into single track round the back lanes of Carharrack. Sweet! :)
