Cauldron Snout, looking downstream
Cauldron Snout is a waterfall on the upper reaches of the River Tees amongst the Pennines. The Tees forms the boundary between County Durham to the north and Yorkshire to the south, though at Cauldron Snout it is just entering upon that duty from Cumberland, the border marked by the falls, and so Cauldron Spout is bordered by all three shires.
The falls the dam of the Cow Green Reservoir. It is well upstream of the famed High Force waterfall. The waterfall lies within the North Pennines Area of Outstanding Natural Beauty (AONB) and European Geopark.
It is more a long cataract than a waterfall, and at 200 yards long, reckoned to be one of the longest waterfall in the land.
Cauldron Snout is impressive amongst the fells and attracts a lot of visitors, despite the 2-mile walk from the nearest car park (at Cow Green Reservoir). The Pennine Way takes in Cauldron Snout.
The falls are caused by the upper Tees passing over dolerite steps of the Whin Sill.
