i may have climbed Ben Nevis ... at the very least, i posted a trip report

i carried snowshoes, ice axe and crampons but didn't use them ... there was snow on the summit, but the ridge walk was mostly bare (late march 2005)
the Tourist Track is the most popular route, but it's a boring switchback of flat stones up to the summit
there's a much more interesting loop over Carn Mor Dearg, if you don't mind leaving the trail, 'whacking up the steep rocky scree slope to Carn Dearg Meadhonach, then following the knife edge ridge around to Ben Nevis' summit, down the Tourist Track
i hiked solo, and reached the knife edge ridge just as fog rolled in ... very spooky, like a scene out of Lord of the Rings ... following the knife edge solo, wondering if i'd be able to find my way over the summit without falling off steep cliffs in thick fog, made this one of the most mentally challenging hikes i've ever done ... probably the only time i've ever felt challenged more mentally than physically
Collins Ramblers Guide to Ben Nevis & Glen Coe is a good source for hiking in this area
Ben Nevis is popular among rock and ice climbers, who ascend the steep icy cliffs up from Charles Inglis Clark Hut ... the loop i checked out was considered "hillwalking" (hiking)
