Why it's Wildland
7.4Built between 1967 and 1971 to regulate the River Tees, Cow Green Reservoir sits high in exposed Upper Teesdale, close to the dark rock of the Whin Sill and the dramatic cascade of Cauldron Snout.
Cow Green earns its place for the way a working reservoir meets a stark, open Pennine landscape: big skies, moorland and the nearby rush of Cauldron Snout. It feels remote and elemental, but there are paths from the car park to explore on foot.

The experience
Start at the Wheelhead Sike car park and follow paths towards the reservoir dam and Cauldron Snout. Allow time to take in the open moorland setting; conditions can be exposed, and the reservoir itself is not for swimming or water sports.
Things to do
Walk towards Cauldron Snout
Follow the path from the reservoir area towards Cauldron Snout, a dramatic waterfall on the River Tees below the dam. Keep to the designated footpaths.
Look for birds across the moorland
The site is promoted for birdwatching. Take binoculars if you have them and watch from paths without straying into protected areas.
Try dark-sky viewing
Cow Green is described as a dark-sky-friendly site. Choose a clear night and check travel and weather conditions before setting out.

Verified history
Cow Green Reservoir was built between 1967 and 1971 to help regulate the flow of the River Tees. The supplied sources describe the project as part of a contested change to the Upper Teesdale landscape, involving water management, engineering and conservation concerns. The dam and reservoir remain visible reminders of that modern history.
Hidden details

A working reservoir, not a watersports venue — The reservoir is a working water-supply feature. The supplied local guide says not to enter it for swimming or water sports; enjoy it from paths and banks instead.
