The South Downs National Park, located only five miles north of the island at Rowland’s Castle, is an 87-mile-long chain of grassy, chalky downland, where the South Downs Way traverses the range east to west. The Harting Downs area is a beautiful spot to begin explorations, and camping can be found just north near Elsted. You can also explore different options for camping near Hayling Island on Hipcamp.
