The Dramatic Cuillins (Scottish Gaelic: An Cuilthionn or An Cuiltheann) are a range of rocky mountains located on the Isle of Skye in Scotland. The true Cuillin is also known as the Black Cuillin to distinguish it from the Red Cuilins (na Beanntan Dearga, known locally as Red Hills) across Glen Sligachan. The Red Cuilins are lower and, being less rocky, have fewer scrambles or climbs.
The highest point of the Cuillins, and of the Isle of Skye, is Sgùrr Alasdair in the Black Cuillins at 992 m (3,255 ft). The Cuillins are one of 40 National Scenic Areas in Scotland
