This path follows the South Tyne River. It starts near Garrigill in Cumbria and finishes at Haltwhistle in Northumberland. It passes through Alston, the highest market town in England. From Alston the path follows the narrow-gauge railway operated by the South Tyndale Railway, before crossing the spectacular Lambley Viaduct.
As you would expect, the South Tyne Trail follows the South Tyne from its Source in the North Pennine Hills to where it joins the River Tyne at Haltwhistle. The terrain is relatively easy, with the highest point on the moors near the Source. For much of its length, the Path is more-or-less flat and follows both the river itself and the former railway line (part of which is now a heritage line for steam trains). The Path is well signposted.
