Ben NevisThe highest peak in the United Kingdom, Ben Nevis looms over the Highland resort town of Fort William and Loch Linnhe below, attracting an estimated 125,000 completed ascents per year. Most hikers take the well-constructed Mountain Track from Glen Nevis on the south side of the mountain and head for the 2,000-foot-high cliffs on the north face. At the summit, you’ll also find the ruins of an observatory, which was permanently staffed from 1883 until its closure in 1904. While the mountain can be quite easily scaled by even moderately experienced hikers, don’t take the task lightly—do so at your own peril and wear layers, as the weather at the summit can be seasons away from that at the base.
