Cuillin of granite, which is paler than the gabbro (with a reddish tinge from some angles in some lights) and has weathered into more rounded hills with vegetation cover to summit level and long scree slopes on their flanks. 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 scenic beauty of the Cuillin has led to it being designated a national scenic area,
