At 4,413 feet (1,345m) above sea level, Ben Nevis is the tallest peak in the British Isles, and its soaring views are just one of the reasons 150,000 visitors come to conquer its slopes every year. It can be scaled via a few different tracks, the most popular (and easiest) of which is called the Mountain Track. The Carn Mor Dearg Arete (CMD for short) is a longer and more demanding route that traverses the notorious north face, while the Ledge Route is a challenging and occasionally confusing one-way ascent. For all these routes hillwalking experience, navigation skills, proper equipment and a high level of fitness are musts.
