In September 1938 Alfred Wainwright, who later gained fame for his Pictorial Guides to the Lake District Fells, made a solitary walk through the Pennines. The following year he wrote up an account of this walk, which was eventually published in 1986 and is still available. A revised route, based on the original walk was developed by David Pitt of the Wainwright Society for today's roads and rights-of-way. Starting in the market town of Settle in the heart of the Yorkshire Dales National Park, the route heads north on the eastern side of the Pennines through the Yorkshire Dales and moorland stretches of County Durham before arriving at Hadrian’s Wall which 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 finishing back in Settle.
