Coire Lair and the Coulin Forest
The track to the station runs up behind a red phone box, then turns right to reach the platform end. Cross the line through two gates (marked 'Private Crossing' but a right of way for walkers) and head up the stony track opposite. After 100yds (91m) you reach a junction under low-voltage power lines. Turn left here on a smooth gravel road to a gate through a deer fence. After 600yds (549m), look out for a waymarker post where a path turns down to the left.
This path goes back through the deer fence, then runs up alongside the River Lair. As the slope steepens above the treeline, a short side path on the left gives a view of the gorge. The well-maintained stalkers' path runs over slabs of bare sandstone. The path eases, then finally levels off in the upper valley, Coire Lair, with a view to the high pass at its head, 2 miles (3.2km) away.
At the point where the valley floor levels off, a cairn marks a junction of paths. Bear right here, between two pools. In 110yds (100m) there is a second junction with a tall, well-built cairn. Bear right, on a path that leaves the corrie through a wide, shallow col just 350yds (320m) above. An elegant conical cairn marks a final path junction. Bear right; in a few steps you're heading downhill. The path runs among drumlins and sandstone boulders, slanting down to the right to join the wooded Allt nan Dearcag. The path now runs down alongside this stream; you may notice pale grey quartzite. The path drops to reach a footbridge across a side stream, the Allt Coire Beinne Leithe, with the Easan Geal, White Waterfalls, just above.
At an open bothy hut, a track continues downhill, with the gorge of the Easan Dorcha (Dark Waterfalls) on its right. After a mile (1.6km) there's a stone bridge on the right. Turn across this, on to a track that runs up the wide, open valley to the Coulin Pass at its head. After the pass, the track goes through a gate into plantations, then bends right to slant down the side of Strath Carron.
At a Scottish Rights of Way Society signpost, follow the main track ahead towards Achnashellach. After 0.75 miles (1.2km) you cross a bridge to a mobile phone mast. Fork left, just before a second mast, and descend gently to reach the junction above Achnashellach Station. From 2014, however, this track will sometimes be closed for tree felling. If so, from Point 5, follow signs down a path to the left. It contours left, then drops quite steeply to a path junction with a forest track seen on the right. Turn right to join this track, which leads to Achnashellach Station.
