A new coastal path opened in 2012, running (walking) from Chepstow to Queensferry. That is near Chester, and where we had left Wales only to get lost among the half-timbers in England. There are some 870 miles to explore along the way. See the Long Distance Walkers Association site, http://www.ldwa.org.uk/index.php ; and The Financial Times, April 28-29, 2012 at Life and Arts at p. 9.
Some 1300 long-distance walk routes are listed at the site.
