Did you know that when the Wales Coast Path opens in May 2012 it will be the only continuous trail on the planet to run the full length of a country's coast! The 870 mile trail would take around 70 days to walk but would take in 18 medieval castles, 11 nature reserves and dozens of beautiful beaches.
