This 10km route 4 follows a rectangle to the north of Middleton-in-Teesdale and is well worth doing for its scenery, views and descents - not to mention the heritage value! The area is shaped by a long history of farming, lead mining and quarrying. Traditional management means that Teesdale is still awash with flower-rich hay meadows. The whitewashed farm buildings of the Raby Estate are a distinctive feature in the upper dale. Please note that the original leaflet was produced and printed in 2005. The routes are still valid but some of the information (e.g. refreshments and facilities) might be out of date.
