1 From the bridge over the beck, turn up the track that goes upstream by the 'Bridleway only, no vehicles' sign. Follow the track for a mile to reach Old Gang Smelting Mills.
2 Continue along the track for another ¾ mile (1.2km), going right where the path forks, following the Level House Bridge sign. Level House, which stood at the junction of the paths, was a dwelling built in the late 17th century for one of the partners in the early mining here. You will see the remains of the rails that took the ore-laden trucks from the mines to the smelting mills along the way.
3 At the bridge, go through a gate, cross the bridge and go uphill. This track follows the Old Rake Vein, towards the Merryfield Mines. Where a track comes in from the left, turn right, following a path down into the valley to cross two streams, past spoil heaps and some small cairns. When you reach a fence, continue ahead with the fence on your right. At a gate in the fence, go through and continue with the fence on your left. On reaching a stony area, turn right to follow a stream valley. Cross a small stream and continue ahead along the track. Go through an area of spoil heaps and shafts, bending right through a bare rocky area to continue along a grassy track, through more heaps.
4 There are views into Arkengarthdale, another heavily mined area, to the right, and you can see the remains of hushes. These were an early method of reaching the ore. At the top of a steep slope a stream was dammed with turf. Once enough water had collected, the dam was breached and the water rushing downhill gouged a trench in the slope, with luck exposing the vein.
5 Where another track comes in from the right go left and follow the track to a road. Turn right and follow the road, which crosses a cattle grid. Go over a footbridge beside the ford at Fore Gill Gate (viewers of BBC television's All Creatures Great and Small series will recognise this as the ford crossed in the opening titles by the vet's car) and ascend the hill, then continue downhill.
6 Before reaching the bridge over the Old Gang Beck, you will cross the horizontal flue from the old Surrender Smelt Mill, downstream to your left. The flue was connected to the chimney up on the hill to your right. Such long flues enabled the smelt mills to use higher temperatures to separate the lead from the slag. Some lead vapourises in extreme heat, and this was previously being lost in the atmosphere. The long flues meant that the gases cooled as they went towards the chimney, so the lead solidified in the walls. Men (though it was often boys) could then be sent into the flues to recover the lead deposit. Cross the bridge to return to the parking place.
