From Dungeness on England's south coast to Conwy in North Wales, Janet Street-Porter sets out on a lively and entertaining marathon journey of over 500 miles. Walking from coast to coast and climbing over 65,000 feet in the process, she travels over the South Downs, passes through the Mendips and the Cheddar Gorge, crosses the Brecon Beacons and the Black Mountains, and climbs Snowdon, to emerge just a few miles from where she used to pick Bilberries on childhood holidays in Wales. Coast to Coast is a feast of surprising discoveries, quirky observations and delighful digressions.
