High Force is one of England's most impressive waterfalls, located in Upper Teesdale, County Durham, within the North Pennines Area of Outstanding Natural Beauty and a UNESCO Global Geopark.

The River Tees drops 21 metres (about 70 feet) in a single uninterrupted plunge over the Whin Sill rock formation into a deep plunge pool below — the highest such drop in England. The underlying geology dates back more than 300 million years.

A short woodland path leads to the base of the falls, and the Pennine Way on the opposite bank offers an alternative free viewpoint.

The landscape surrounding the falls takes in open moorland, hay meadows, and mixed woodland that shift dramatically with the seasons. Artist J. M. W.

Turner famously painted the scene in 1822, and it remains a draw for photographers, artists, and nature enthusiasts today.
