The grassy hills of the Cheviots have created a number of crags which are quite unlike others in the region, the most notable of which are the Henhole Crags.

These crags, which are all composed of lavas, are situated on both sides of the College Bum high on the west side of Cheviot, the highest mountain area in Northumberland. The Igneous rock means the crag dries quickly after rain providing good climbing routes in the lower grades.

Other crags within the Cheviot Hills include Bizzle, Dunsdale, Langlee and Housey.
