In reply to peebles boy:
Creag Meagaidh might tick most of your boxes?
It's on the geographical limit (next to the A86), very good snow-holing potential and some ridges of varying difficulty.
Day 1. Aberarder car park: walk up Coire Ardair to the loch below the main crags, then turn sharp SE and up towards Coire nan Gamhna - a lovely spot- (GR 445877) & ascend the broken ridge up R from the lochan. Gain the plateau and go for 'Meggie summit, or work your way carefully to The Window for your snowhole.
Day 2. Over Stob Poite Coire Ardair and follow the plateau to the Min Window, then onto to Carn Liath, descending to Aberarder.
(Variant: ascend excellent East ridge of Coire Chriochairein from Coire Ardair then overnight at The Window snowholes & the following day complete 'the round' descending via Sron a Ghoire to Aberarder.)
Other ridges: Creag Mhor ridge - rambling and indistinct to start, fairly gentle but a good way to the summit plateau. Also good snowholing potential just off this ridge (GR 445868). You'd need to start near Moy Lodge or, better still, from Coire Chomharsain - parking at Aberarder.
East ridge of Beinn a Chaorainn - bit of a schlep getting to the bottom of it but it's an airy Alpine-like ascent.
Other popular snow-holing spots in 'Meggie area: (GR 463903) - handy for the Carn Liath plateau area.
Needless to say, navigation and general mountaineering skills need to be to the fore for anything up high on 'Meggie.
Hope this helps!
