The north face of Ben Nevis is riven with buttresses, ridges, towers and pinnacles, and contains many classic scrambles and rock climbs. It is of major importance for British winter climbing, with many of its routes holding snow often until late April. It was one of the first places in Scotland to receive the attention of serious mountaineers, with an ascent of Tower Ridge in 1892 the earliest documented climbing expedition on the Ben. (It was not climbed from bottom to top for another two years). The Scottish Mountaineering Club's Charles Inglis Clark hut was built below the north face in Coire Leis in 1929. Because of its remote location, it is said to be the only genuine alpine hut in Britain. It remains popular with climbers, especially in winter.
