The Yorkshire Dales is one of the twelve National parks of England and Wales. The Dales is a collection of river valleys and the hills among them, rising from the Vale of York westwards to the hilltops of the main Pennine watershed.
The characteristic scenery of the Dales is green upland pastures separated by dry-stone walls and grazed by sheep and cattle. The dales themselves are 'U' and 'V' shaped valleys, which were enlarged and shaped by glaciers.
The word dale comes from a Nordic/Germanic word for valley.
