Walking may be in moorland areas where you may cover long distances in remote countryside and the terrain will often be rough underfoot. In mountainous areas you will encounter some sustained ascents and descents and occasional sections of scree. Ascents and descents will be between 400 and 600 metres but over about two hours where some of the gradient may be very steep. In mountainous areas where you can expect rocky terrain and continuous ascents and descents, walks may visit high summits and ridges, so you will need a good head for heights, and not suffer from vertigo. There may be some easy scrambling.
