Rather like Ardverikie Wall, this has been a painfully obvious gap in my mountaineering CV for decades. I'd arrived in Glen Brittle fairly late yesterday evening, and found it unsurprisingly tricky to get a partner for this - as it requires a long drive back in the direction most people had just come, so was not a very logical choice for the first day on Skye! However, unlike the rest of the hut residents, I only had a couple of days so had to maximise my time, and wanted to fill in those obvious gaps. Eventually, an ideal little team emerged: Simon M agreed it would make a nice 'active rest day' in advance of our ridge attempt on Monday, and new AAC member Elaine arrived at the last minute. We drove round to Loch Slapin, last visited with the family in 2012: stunning views across to Blaven, one of the most famous and best views in the UK, with the entire ridge etched black against a deep blue sky. The car park was full, so Elaine (who had detailed local knowledge) introduced us to a connoiseur's route, very much my cup of tea, up the untravelled valley of the Allt Aigeann. This was superb: completely empty, following a delightful stream as the valley twists right then left and becomes a tight rocky gorge. Some tricky scrambling allowed us to escape the gorge, then fairly solid scree led to the big bealach between Garbh Bheinn and Sgurr nan Each. It clouded over a bit temporarily, and a fierce northerly blasted into us when we emerged - uncomfortably cold for a while. We skirted the highpoint of Sgurr nan Each, and the wind dropped quite a bit as we approached the mighty Clach Glas - which looks stupendous from this angle, the 'Matterhorn of Skye' as it is often called, a spire of black rock. At another col, numerous gendarmes and pinnacles dot the lower section, which are turned on the right. Above some exposed slabs give good scrambling to a narrowing of the ridge where it begins in earnest. More twists and turns lead to a scree gully, and then a rightward slanting shallow chimney which is key to the route. I led this on my half rope and Elaine was happier this way: Simon soloed alongside. At the top, the route heads left up superb open slabs, easy but exposed throughout. I led a long pitch up the slabs, heading right at the top to a belay, then led up gabbro shelves to the superb summit: this entire section is wonderful, as good as anything of its kind in the British Isles. It was sunny again, with stupendous clarity of light. The views were magnificent in all directions - across to Blaven, then back to the Cuillin outliers, then across to the main ridge, all of which is visible from this angle. The peaks of Knoydart, Torridon and Sgritheall all glistened with Friday's fresh snow, and the panorama stretched from Jura in the south to Fisherfield and the Outer Hebrides. After a snack, the traverse continues. We stayed roped up for the crack that leads to the tricky downclimb of the 'Imposter'. This is the famous, photogenic spire at the top of the south ridge. it looks improbable from below, but - as its name suggests - is much easier than it looks. The bottom basalt section is a tad awkward, however, and very exposed above Choire a'Caise. After this, difficulties ease but the ridge remains narrow and superb, dropping down to the left via a gully lower down, absorbing scrambling throughout with numerous surprises and detours required before the obvious haven of the 'putting green' is reached. This is a grassy col between the two peaks and an obvious lunch spot, with the Great Prow towering nearby. Then comes the route up the north flank of Blaven. This has a steep wall with good holds before slanting right then left to gain a scree slope below the 'half crown pinnacle'. On the right is the 18m chimney, which was a cold but atmospheric line with two good threads and good gabbro holds on the right wall. I brought Elaine up and we then dumped the sacks at the mini-col before walking to the top of Blaven via the broad east ridge in perfect weather (although it clouded over just a tad at the summit). A very long descent down to Coire Uaigneach, where the route kinks round, back to the shores of Loch Slapin and the car on the other side of the lake. Nice to tick this classic route at last - perhaps the best route of its kind in the UK. Alpine PD+.
