The waterfall is fed by the Cow Green Reservoir, with water running over a dam wall and then plunging into the river.

Cauldron Snout is a stunning series of waterfalls accessible from the Pennine Way, and the large car park at Cow Green Reservoir. There is a rocky footpath that is a bit of a scramble leading down to it from Cow Green Dam; the latter makes a super nice backdrop to the first waterfall. This footpath is treacherous when wet, and you need to be very careful, a fall could have serious consequences.

Sandwiched between Cross Fell and Great Dun Fell is Little Dun Fell. This is a super hill to do, and the walking route to it from both of the aforementioned hills forms part of the Pennine Way, so it is slabbed with stone and well maintained. Little Dun Fell, however, is somewhat overshadowed by its more famous northern and southern neighbours, but I prefer this hill to the others. The views across to Cross Fell and Great Dun Fell are super nice, raw, and barren, with nothing in between just the path of the Pennine Way. It also has a small cairn on the top, and at 842 metres, it is also a UK-designated nuttall.

Mickle Fell is the highest peak in Yorkshire, depending on which list you look at. It is an imposing bulk of a mountain and difficult to get to as a large chunk of it is in the Warcop military training range and access is limited. Normally, 10–12 weekends are set aside annually by the military to allow hikers to walk one of two routes to its summit. There are two routes: the Northern Route and the Southern Route, and both require permits. I did the Southern Route, which is a linear route following a fence for most of the way. The middle section of this route is difficult and boggy. For further information, scheduled hiking days, and contact numbers, see the links below.

At an altitude of nearly 800 metres, you'll find this summit and its cairn, which can be the ideal prelude to continue on to Great Dun Fell and break the 800 metres barrier.

An impressive climb to the waterfall, the roar of the water and the view into the depths quickly humble you. Pay close attention to the steps, smaller climbing units are necessary. Keep well to the right of the rock and if the rock is not immediately visible, use trekking poles to test whether the ground holds, otherwise you won't be able to enjoy the view from above.

The natural monuments in Moor House National Nature Reserve are primarily shaped by the Great Whin Sill, a hard, volcanic rock outcrop formed around 295 million years ago. This geological formation is responsible for dramatic features like the waterfalls of the River Tees, where the water plunges over resistant dolerite layers. Glacial activity also played a significant role in carving out the landscape, contributing to the rugged topography and the formation of the fells.
Yes, the reserve is home to several spectacular waterfalls along the River Tees. High Force Waterfall is one of England’s largest, with the River Tees dropping 21 meters into a plunge pool. Another unique and dramatic site is Cauldron Snout Waterfall, where the River Tees descends spectacularly over dolerite steps of the Whin Sill, offering a challenging scramble.
Moor House National Nature Reserve is renowned for its rare arctic-alpine plants, which are remnants of the Ice Age and thrive in the lime-rich soils. You can also find England's largest juniper wood near the banks of the River Tees by High Force, adding to the reserve's unique biodiversity.
For extensive views, consider hiking to the summits within the reserve. Little Dun Fell offers panoramic vistas across the surrounding fells and is part of the Pennine Way. While challenging to access, Mickle Fell Summit Cairn also provides imposing views, though access is often restricted due to military training.
