Start : The Lothian Transect Route begins at Harthill Services.
(S/E) Alight from the X900 Edinburgh to Glasgow Express bus at Harthill Services (cafe, toilets). Walk South-East, up the service road, towards Harthill village (A).
(1) Bear right towards the far corner of a football pitch, and onwards along Dunn Terrace through the outskirts of Harthill. Turn right uphill at Westcraigs Rd. to reach the prominent Harthill Church (St Andrew’s) at the junction of the B718 and B7006.
(2) On reaching Harthill Church head left, along the pavement of the B7006 to the true start of the transect - the Border of North Lanarkshire and West Lothian. Still on the pavement keep on ahead proceeding Eastwards past Greenrigg (B).
(3) On crossing the nascent R Almond, step left through the low fence and take a footpath into the trees of the delightful Polkemmet (C) Country Park. Follow woodland paths that wind alongside the river bank. Cross the river at a rustic bridge, and carry onwards over lawns to the Centre (toilets, cafe, owl centre).
(4) On leaving the Polkemmet Country Park Centre pass to the right of the old walled garden (now a bowling green), and bear left to follow a woodland track along the bank of the river. Carry on to the far end of the golf course and visit the Polkemmet Horn (beside the motorway).
(5) Leave the Polkemmet Horn (D) by retracing your steps 100m to cross the Almond at a small bridge. Head south following a track along the outside of the golf course. Regain the B7006/A705. Go left. Cross before the large roundabout. Turn right beneath the electricity power lines.
(6) Keep on (South) and gently uphill along Polkemmet Rd. When the housing on the left ends (at Burnhouse), and before an industrial estate is reached, go left along the old railway line (Town Walk). Pass schools to your right to cross the A706. Here veer slightly left, beside a high, old wall, to visit South Whitburn Church (E).
(7) Exit the South Whitburn Churchyard, go on through the War Memorial Park, past the Community Centre, to join the White Burn. Follow the burn downstream. Cross near Blaeberry Park. At a minor road, re-cross to the left bank. Carry on downstream.
Cross back again at a small pedestrian bridge. At this point head back upstream, 100m or so, to turn up, and left, to join a footpath along a shelterbelt, behind housing.
(8) Keep to the path as it meanders along more shelterbelts, at the back of the land belonging to the Bickerton Lowland Crofts. We are heading for East Whitburn bing (E). Go directly over a minor road. Almost immediately cross the old East Whitburn to Foulshields railway line and go slightly left onto the gentle slopes of the refurbished bing. At the first junction take the right hand path heading due East. This path rises, through conifers, before branching right into a clear area atop the bing. Admire, or be bemused by, the kitchness of the dog cemetery.
(9) Keep ahead over the level summit of East Whitburn bing, and set off South-West across scrubby open ground to find a rough path that leads back down to the old East Whitburn to Foulshields railway line. Turn left along the line.
(10) Soon drop down to take the footpath, to the right, beside a small stream. The path winds about, but shortly emerges onto a minor road. Follow the road, left, to a T-junction. Turn right then left at the next junction to take Hen’s Nest Rd towards Bents.
Proceed along Hen’s Nest Rd. In an entrance way, on the right, just after the old county boundary (stream), find a footpath that parallels the road. Eventually the minor road is rejoined and followed to the B7015 at Bents.
(11) Turn left (old signpost) taking the road into Stoneyburn. Near the middle of Stoneyburn turn right down Meadow Rd. and near a play area take the path that leads straight on. Once across the R. Breach follow the left-hand path to rise through woods over the gently landscaped Loganlea bing (G).
(12) Once through the woods of Loganlea bing turn left at the minor road into Loganlea. Proceed along the main Loganlea drag. After Loganlea Rd. crosses an incised stream, turn right up Addiebrownhill.
(13) Just before the railway bridge, turn left along the footpath beside the railway. The path leads you directly to Addiewell Railway station, where this first section of the Lothian Transect Route ends. (S/E)
