The west end of the route is just north of a small road bridge over a disused railway at Clarkston / Airdrie at Grid Ref NS 78123 66264. There is a signpost at this end of the path, but no sign on it (it currently displays a sign about dumping of rubbish).
A metal field gate prevents vehicular access, but there is a wooden pedestrian slip-through at the side. In all but the driest weather this access is difficult to use, due to a large puddle which forms inside the field. A grassy tractor-track leads gently uphill, through open grazing land, northwards briefly then veering north-east at Burnhead Quarry, Thus far, the route is strictly SM 8, which continues ENE as the tractor track, but at NS 78168 66507, (No signpost) SM 9 now diverges, following the remains of the fence NW around the edge of the quarry.
This leads to a broken gate at NS 78029 66646. The route is now only a trodden line in the grass, apparent as a ‘shelf’ running obliquely up the slope ahead, passing below a prominent patch of gorse.
Once the slope eases, a fence surrounding Airdriehill Quarry can be seen, with warning notices, and at this point a rutted tractor track is followed, leading to a telecommunications mast, at a group of ruined buildings, and the route leads directly towards these. On arriving at the mast pass around it’s NE side, and a gate is visible next to the ruins of Airdriehill House at NS 77627 67004.
The access track (stony / vehicular) is then followed downhill to the public road at GR NS 77514 66983. There was once a gate here, but this has been permanently fenced off – in response no doubt to the horrendous amount of fly-tipping – with a currently unblocked pedestrian gap at the side. There is no stile or slip through.
There is no signpost to show this is the start/end of the right of way. There are good distant views, including Tinto and Arran, and a large amount of rubbish.
