V-shaped

The narrow valleys make up the largest proportion of the area. They cover a wide variety of landforms, from gorges and ravines to U-shaped valleys, but they are all upland stream or river corridors, draining directly from the upper plateaux. The land cover variation is also great, ranging from moorland to conifer plantations, and inbye pasture to mixed woodland and thick broadleaved woodland. A number of these valleys have also been flooded to form reservoirs, creating further variety. There are eight narrow valley landscape types.
