From the city of Chichester with its ancient walls and harbour inlets standing sentinel over the English Channel to the northern heights of Black Down on its ridge of greensand above the intervening folds, farms and villages of the western Weald, from the bustling towns of Crawley and Horsham in the lee of the chalk slopes of the South Downs to the traditional seaside resorts of Littlehampton and Worthing, the 40 circular walks in this guide offer plenty of scope to explore West Sussex's famed downs, woods, heaths and nature reserves, along with its villages, stately homes and country estates.
