 North of Hadrian's Wall and the Tyne Valley, the land rises to form the Cheviot Hills, which extend into Scotland and could probably be considered part of either the Southern Uplands or the northern Pennines.They are included in Northumberland National Park, along with Kielder Water and the Kielder Forest.The North Pennines (an Area of Outstanding Natural Beauty, or AONB) lie south of Hadrian's Wall, and east of the Lake District, from which they are separated by the Eden Valley.
