Ben Nevis

The Ben is Britain's largest hill and stands at 4,406 ft (1344 m). Many an experienced walker has perished walking off Ben Nevis' cliffs and while there is a great path which takes you on to the summit plateau, it can be treacherous while heading on the plateau, especially if you don't how to use a map and compass properly and are ill-prepared for the potentially awful weather. As with all Munro's, if you're heading on to the hill, take plenty of warm (and waterproof) clothing, food and water.

I did the Ben as my first Munro back in 2002 and I loved most of it (zig-zags aside), heading up the 'tourist' path. I wasn't prepared for what people wore on the way up. Sandals, shorts and all this in May, while there was still quite a bit of snow on the peaks. Take decent shoes and enough clothing FFS; it will take you between 5.5 and 7 hours to get up AND down this baby. It's not technically difficult but in Winter, this is a major undertaking - consider that for every 100m climbed, this equates to a 1 degree C drop in temperature - the summit will feel at least 11 C colder than the car park and add in the wind chill and you could be venturing up into very cold conditions indeed.
