(S) From the parking area at Glengavel Reservoir, walk along the road with the water on your left-hand side.
(1) When you reach the fence-line turn left (South East) towards the boathouse and go through a gate in the fence down by the water's edge.
Follow a grassy footpath along the edge of the reservoir, through a large metal gate and alongside a dry stone wall.
(2) On reaching the edge of the forest, veer left to go through another large metal gate and follow the tree-line south east for 400m to reach a clearing in the trees.
Turn right (South) across some boardwalk and follow a grassy path uphill to the remains of two wooden huts.
(3) Just before the huts, look out for a footpath heading steeply uphill on your right (can be overgrown with fern in summer months).
Once up the initial steep section, follow a faint trail through the heather. You'll soon reach a point where it is difficult to get past the trees on your right, and you'll find it easier to go into the forest and turn left along one of the rows of trees.
(4) When you come out the trees carry on straight ahead (S) for approx 200m to a clearing. Turn right (W) and walk through the clearing for almost 1km, heading for the wide turbine directly ahead. There is no path here so take care on the tussocky heather.
(5) You are now in Bankend Rig Windfarm. With the turbine to your left, follow the track right (NW). The track heads downhill towards a quarry.
(6) Turn left (West) when you reach the quarry, keeping right at a fork a little further along.
(7) Approx 2km along this track you will reach a small pond on your right-hand side (makes a good lunch stop!). Ignore a path off to the left here, keeping right (West) to emerge out of the forest onto open moorland.
(8) Continue along this track for 2km, passing a sheep fold, to reach a fork. Turn left (North West) and pass through the farmyard at Burnhead Cottage.
(9) Follow the track beyond the house for 700m to a fork. Turn left (South West) - signposted "Long Cairn Walk", passing between two properties at Saughall.
(10) Follow the grassy track along the field edge to a gate. Pass through the gate and continue ahead (South West), downhill towards the Tulloch burn. There is a ford here and a footbridge to the right.
(11) Cross the bridge then follow the track uphill, enjoying fine views of the Long Cairn at the top.
Continue along the farm track for approx 1km, passing Loanhead and Loanfoot farms en route.
(12) At the road-end turn right (North) downhill to Bransfield Farm.
(13) At a crossroads next to the farm, turn left (South West) towards Bransfield Bridge.
(14) Just before you reach the bridge, look out for a wooden gate off the road to your right, leading into some woodland. Go through this gate and follow the path alongside the Gower Water/Logans Burn (depending on what map layer you are looking at!).
(15) When you reach the road, turn left (South West) to cross the bridge.
Follow the road downhill for 1.4km, passing High Greenbank Farm along the way.
(16) At a crossroads turn right (North) to cross Randoldcoup Bridge. Walk along Randoldcoup Road for 400m to reach West Main Street, Darvel (E)
