Click the map for tourism ideasNorth Yorkshire, one of England's largest counties, consists of two separate upland areas: the Pennine Chain in the west, and the Cleveland Hills and Yorkshire Moors in the east. The county encompasses two National Parks: the Yorkshire Dales with its green valleys, rivers and streams and the heather-covered North York Moors scattered with prehistoric remains. The beautiful medieval city of York is the county's chief commercial centre that traces its history back 1,000 years to Viking days.
