NCN 70 is "Walney 2 Wear", but W2W can also be "Walney 2 Whitby", and that's NCN 165 - an alternative eastern end to this coast-to-coast route. W2W is tough and the Whitby finish tougher still, with some truly gruelling climbs over the North York Moors. The views from the summits are fabulous, and the precipitous unpaved descent to Eskdale is certainly unforgettable.
