The main mountainous islands of Scotland

The main mountainous islands of Scotland are Skye, Mull and Rùm in the Inner Hebrides and Harris within the Outer Hebrides, however

Islay, Jura and, although separated from the Hebrides, Arran are all very well-regarded for their hills and mountains. Skye’s Black Cuillin, composed of basalt and rough gabbro, is generally regarded as the most serious mountain terrain in Britain with bare rock,

jagged in outline and steep cliffs and deep cut corries. Ropes are required for some summits and the area is host to the only Munro necessitating climbing apparatus, the In Pinn. The neighbouring Red Cuillin is composed primarily of granite and has more

isolated, cone-shaped mountains of a slightly lesser height. Skye is also very well known for the Quiraing and its Old Man of Storr on the Trotternish peninsula. The isle of Rùm has its own Cuillin, also composed of gabbro but shorter, grassier;

necessitating good scrambling ability, and a head for heights. Multiple characteristic smaller hills are to be found on the island as well.
