Hill data from the Database of British & Irish Hills v18.3 (CC BY 4.0). Prominence is the drop to the hill's key col; a dash means it is not recorded in our dataset.

Browse the other survey areas on the regions hub, check what you can do at a specific spot with the access checker, and read oursafety notes before heading up — hill days here can outlast daylight, especially in winter.
