Langdon Beck Youth Hostel, just East of Langdon Beck. Grid Reference NY895304. Park outside of the Youth Hostel unless you have permission to park in the small car-park itself.
A walk of approximately 9 miles, crossing pastures, moorland and walking alongside the River Tees in Upper Teesdale. Rare Gentians can be seen in late spring, just off the access road from Cauldron Snout. Keep to the road. It is best done in Summer when dry weather is forecast, due to the location of this walk the average temperatures of the region have a climate similar to Reykjavik in Iceland. Dippers and Ring Ouzels can be seen near the River Tees.
Walk down the road, heading East, for 60 yards or so. There is a footpath going down a farm access road on the right. Take this public footpath and head towards New House Farm, straight in front of you, crossing stiles and gates as appropriate. Once past the farm, the track leads down and then forks. Take the right fork heading towards Saur Hill Farm, crossing the bridge over Harwood Beck. Go right up to the farm and then up over the field to the left heading in a diagonal direction, at the time of writing a big 'PW' (Pennine Way) was sprayed on the fuel tank to the left of the farm. This will lead you to a stile in a wall, marked white, keep crossing these fields using the same white marked stiles until you eventually come alongside the River Tees.
On the other side of the river is Cronkley Scar which should be directly in front of you. Continue along the river, heading upstream, past Widdybank Farm through more riverbank pastures. Please keep your dog on the lead to avoid disturbing the cattle here.
Keep following the clear path alongside the river, sometimes along boardwalks to avoid the worst of the bog, eventually passing underneath Falcon Clints. Maize Beck joins the River Tees here and Cauldron Snout now comes into view. Climb up the rocks to the right of the falls, taking care because the spray from the water can make them very slippery.
Once at the top, the dam of Cow Green Reservoir appears. Follow the road to the right of the reservoir as it climbs Widdybank Fell, past the weather station, which is over to the right. If you are here in late Spring, look on the verges for the Spring Gentian, an intense blue alpine flower. Follow this road up to where it meets the main Langdon Beck/Cow Green Reservoir road and turn right to descend.
Follow this road down, through gates, all the way until the road crosses Harwood Beck. Do not cross, but take the footpath to the right which follows Harwood Beck back to the bridge which you crossed before going up to Saur Hill Farm. Cross the bridge to the left and proceed back up to New House farm and then return back to your car.
