High Force

High Force is a waterfall on the River Tees, near Middleton-in-Teesdale, Teesdale, England. The waterfall is within the North Pennines Area of Outstanding Natural Beauty and the European Geopark. The whole of the River Tees plunges 70 feet over a precipice in two stages. After heavy rainfall the river will also flow over the usually dry right-hand side channel, creating two falls. Very occasionally the river level will be high enough to flow over the central section of rock; the last recorded time this happened was in December 2015 after Storm Desmond. In harsh winters the falls have been known to freeze, creating cathedral-like ice formations.

Access to the northern bank is via a private footpath on the Raby estate for which a fee is charged. The southern bank can be reached free of charge via the Pennine Way public footpath which crosses the Moor House-Upper Teesdale National Nature Reserve.
