Trotternish ridge at Sunrise, Culnacnoc, Isle of Skye

Trotternish or Tròndairnis (Scottish Gaelic) is the northernmost peninsula of the Isle of Skye, in Scotland.

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.
