One of its more well-known features is the Trotternish landslip, a massive landslide that runs almost the full length of the peninsula, some 30 kilometres (19 mi). The landslip contains two of Skye's most famous landmarks: the Old Man of Storr, an isolated rocky pinnacle, and the Quiraing, an area of dramatic and unusual rock formations. The summit of The Storr, on whose slopes the Old Man of Storr is located, is the highest point of the peninsula. While boasting many vertical heights, the area is mainly unsuitable for rock-climbing due to the friable rock.
The most northerly point of Trotternish, Rubha Hùinis, is also the most northerly point of Skye. The three major settlements on Trotternish are Portree (generally regarded as the capital of Skye), Uig and Staffin.
In terms of number of speakers, Troddernish is the strongest Gaelic-speaking area of Skye. In the 2001 census, 61% of the population returned as Gaelic speakers, there are Gaelic-medium units in the Staffin and Kilmuir primary schools, and the area is the focus of one of Comunn na Gàidhlig's Gaelic development initiatives, Lasair. In 2010, Comunn na Gàidhlig named Staffin as their Gaelic Community of the Year.
