Info from Pennine Journey website
"The Pennine Journey is a challenging circular walk, 247 miles long, passing through the wonderful variety of terrain and scenery that the north of England offers and touching on all the major rivers in the region. Starting in the market town of Settle in north Yorkshire, in the heart of the Yorkshire Dales National Park, the route heads north on the eastern side of the Pennines through the delightful Yorkshire Dales and moorland stretches of Co. Durham before arriving at Hadrian’s Wall. This World Heritage site, in the Northumberland National Park, is followed for 21 miles until the route heads south on the western side of the Pennines. After traversing the Pennines just below the highest point of Cross Fell, it enters and travels down the Eden valley before skirting the Howgills Fells then arrives back in Settle."
