River Greta Source to Mouth (United Kingdom)
The River Greta rises in the Pennines and drains Spittal Ings, Roper Castle (or Round Table) and Beldoo Moss to the east of Moudy Mea, before running east through Stainmore Forest. The trail starts at the tributary from Black Riggs and runs down from the high Pennines down through Bowes, where, close to the site of the Roman fort of Lavatris it is crossed by the Pennine Way. It then flows down through Teesdale north of The Stang Forest, through historic church sites at Brignall and on to Greta Bridge hamlet.
