From St Bees to Robin Hoods Bay and 190 miles this is a challenging route. Devised by the late Alfred Wainwright in 1973 to link the Irish Sea and the North Sea via the hills, moors and valleys of Northern England. The route crosses three National Parks: the Lake District, Yorkshire Dales and the North York Moors. It is scenic, but high-level, including some fairly demanding upland stretches, and visits only two towns of any real size, Kirkby Stephen and Richmond - ideal if you want to get away from it all.
