Found this place by chance, if your up this neck of the woods check it out..

this is a much better walk to High Force, good directions at the visitors centre and the lady was dog friendly ( a sprocker owner ) dogs allowed

Cross the Tees to the Pennine Way

Teesdale in all it,s glory, keep going to Nora Batty land or Derbyshire if you like

another footbridge about a mile up stream nearer HF

High Force from the Yorkshire side

And a plodge in the Bowlees Brook when you get back
