In reply to JohnnyW:
Back in the days when we didn't know any better, my mate and I once took a taxi up to Achlean at about 7pm on a fairly bad New Year's Eve, rucksacks brimming with inflatable curry, brandy pudding, and malt whisky, aiming to walk the 3 or 4 miles of wide flat easy track up the glen to Ruigh-Aiteachean and have our Hogmanay there.
Hah! We stepped out of the taxi and the wind nearly blew its door off. Before we could change our minds and get straight back in, the taxi scorched off (the driver had been telling us about his plans for getting hammered in Aviemore once he'd dropped us off, we were his last run before he stopped) and before we could open our map the wind had shredded it. By the time we'd got head-torches on we were freezing. We stumbled around bent double for half an hour trying to find the path out of Achlean farmyard; force 9 or 10 in the air, ice everywhere underfoot.
We ended up feeling our way back to the road, were quite relieved when we located it, and walked back 2 or 3 miles along it to the nearest B & B.
This was emphatically the correct decision
