Most of us have walked at least a section of the South Downs Way, or followed a rural a bit of the South Downs or followed one of the many rural walks that Sussex can boast, but what about the county's fourth wall-the sea? If you want to feel the salt on your cheek, take in a bit of bird-watching, some beach-combing, a pinch of history, a sprinkling of local gossip and just enough geology and geography not to numb your brain, then come with local expert David Arscott on a walk along the Sussex coast.Starting from the sands at Camber and sticking as close to the water's edge as possible, the route shows how environmental changes, human interference, events, disasters and the power of the sea have affected the county's coastline, leaving harbours stranded high and dry and villages drowned off shore. You don't have to do it all in one go (it's a long walk!) as it's broken up into easy sections, but whichever part you tackle, "A Tour along the Sussex Coast" makes an ideal hand-held companion to take along with you.
