Wilderness Landscape & Natural Heritage
High Force Site of Special Scientific Interest (SSSI) is located in the North Pennines Area of Outstanding Natural Beauty, within County Durham, England. It protects the area surrounding High Force, one of the most impressive waterfalls in the United Kingdom, where the River Tees plunges 21 meters (about 70 feet) through a dramatic gorge formed by layers of dolerite and limestone. The site is recognized for its exceptional geological formations that reveal significant information about the region’s volcanic past and glacial history. Ecologically, the SSSI supports diverse habitats including upland heath, woodland, and grassland, which sustain a range of plant and animal species, some of which are rare or specially protected. Notable species include native birds such as peregrine falcons and dipper, as well as specialized mosses and ferns adapted to the moist, rocky environment. The area around High Force has a rich cultural history with evidence of historic mining and farming activities. Visitors are attracted to the site for hiking, birdwatching, landscape photography, and appreciating the natural power and beauty of the waterfall. The surrounding trails provide accessibility to viewpoints overlooking the falls and the gorge, while nearby paths connect to the broader network of trails in the North Pennines. The SSSI designation ensures that the natural environment and geological features are maintained and monitored to protect their scientific and educational value. The site draws many visitors annually who come to experience the panoramic views, observe wildlife, and explore the geological heritage of this distinct English landscape.
