It's a total slog at times. I've walked it twice with different people. The second time we walked right up to the loch Sloy dam and headed straight up from there. If you thought the regular way was steep then try that way. Theres no path either so it was a map and compass job all the way.
Walked Ben Vorlich across the valley in an equally stupid way too. I suppose a hill is a hill no matter how you get to the top. I like that part of the world, it's the closest to where I live and we often head up that way.
