NN6050638311 Take the track roughly southwest for a few hundred metres, then turn right onto an obvious and well-trodden path. This climbs west for just over 1km onto the broad crest of the ridge, which it then follows north to Meall nan Tarmachan's south top (spot height 923m). Bear northwest from here across a little saddle and a fence, then climb quite steeply through a tier of scrappy crags before curving left to reach the summit. This ascent can be tricky in deep snow or poor visibility.

NN5849239036 Descend a clear path, initially south and then southwest, passing a pool on a broad saddle to enter lumpy bumpy ground above the cliffs of Cam Chreag. From here a short steep ascent leads to the sharp peak of Meall Garbh, the best summit on the round.

NN5780138290 Heading west a brief descent brings you to the famous arete, a narrow level crest with an entertainingly airy feel. Unfortunately it's so short that you could almost miss it if you blinked at the wrong moment. The crest then broadens as it drops west towards the next col; but just before this saddle is a bad step, unseen until you reach it. This short rocky descent is only likely to prove awkward if it's wet or icy, and in fact there's a less problematic line just north of the obvious worn path. Beyond the saddle the path weaves over two minor peaks before climbing to the summit of Beinn nan Eachan – all a bit confusing if it's misty.

NN5701638372 To get off Beinn nan Eachan bear a little right in descent to bypass some crags. Then there's more of that knobbly confusing ground as the ridge begins to swing south, climbing to the grassy summit of Creag na Caillich. From here keep following the high ground south over some mini tops. Below is a col, and again the best descent to it is to err slightly right to skirt a craggy patch.

NN5631436759 At the col turn left, descending scree under the rambling crags of Creag na Caillich to reach an old vehicle track. Now just follow this back east across the moor below the Tarmachan peaks - with luck you'll have a view of everything you've just climbed.
