Climbed it with my mate Steve Perry, who I'd joined for one day of his 4-month non-stop 1600-mile walk to bag all the Munros in one winter season. He's the first and so far the only person ever known to have done this. I went home afterwards, he carried on walking for 15 more weeks!
We came up the north side, which is virtually pathless and a great contrast to the busy motorway of a path from the south. Then descended and carried on along Loch Lomond to the pub at the northern end (name escapes me...Inver-something Inn?). We saw no one in 8 hours.
