Ben Nevis is the tallest mountain in the UK. At a height of 1,344 metres (4,406 feet) it dominates the skyline of the Highlands town of Fort William which nestles beneath it. There is a walkable route up to the summit of the mountain during the summer but even so the changeable weather and inexperience can catch the unwary. In winter the peak of the mountain is invariably snow-covered for several months and this, along with only brief hours of daylight mean that a winter climb should only be attempted by experienced hikers or mountaineers.
