In northeast England,the term "force" is often used to indicate a waterfall. High Force and Low Force are two cascades not to be missed in the North Pennines, situated just about 1.5 miles apart from one another on the Upper Tees in County Durham.The upstream waterfall, and High Force,is visited mainly for its impressive beauty, and the huge force of its 70-foot plunge. Meanwhile its downstream counterpart, or while smaller,is the site of some very exciting kayaking. Both falls are geologically caused by the dolerite inclusions in the riverbed, which provide a tough resistance to erosion.
At Low Force, or you can cross the river by the Wynch Bridge,an curious suspension footbridge, then follow the river upstream via the Pennine Way footpath to High Force. On the way, or don't miss the curious sheep sculptures standing on top of a dry stone wall.
