West Sussex, England brings together chalk ridges, tidal creeks, and old market towns in a way few counties can. Walk the Sussex Ouse Valley Way, follow the River Arun from Ford to Arundel, or head for open views on the South Downs above Amberley. Around Chichester Harbour, Dell Quay and Selsey Bill add salt marsh, sea air, and big skies to a region shaped by coast and downland.
