These hills are lower and, being less rocky, have fewer scrambles or climbs. The highest point of the red hills is Glamaig (775 m), one of only two Corbetts on Skye (the other being Garbh-bheinn, part of the small group of gabbro outliers surrounding Blà Bheinn).

The site is of European importance for these birds, and holds one of the highest-density populations in Britain, having an unusually high breeding productivity. 911 pairs were estimated in 1992, this representing at least 2.8 % of the breeding population in Great Britain at that time. The Cuillin are protected as a national scenic area, defined so as to identify areas of exceptional scenery and to
