Teesdale



The River Tees rises on the Eastern flanks of Cross Fell before flowing east through Teesdale, eventually reaching the sea at Middlesborough. Traditionally it marked the boundary between County Durham and Yorkshire.

The valley is marked by frequent intrusions from the erosion resistant volcanic rock of the Whin Sill. This produces several highly distinctive scars and numerous waterfalls.

The two main waterfalls on the Tees, High Force (pictured above) and Cauldron Snout (a series of rapids the end of which is pictured below), have a rare combination of height and quantity of water making them truly dramatic sights.

There are several other waterfalls of note in the valley including Low Force, Bleabeck force and white force and the Tees remains of real interest up to Barnard Castle.

As the valleys main interest derives from the waterfalls rather than the surrounding hills it is perhaps best visited in Spring or Autumn with Langdon Beck making a good base for exploration.
