The Sussex Border Path is a 150-mile (240 km) long-distance walking route that follows the county boundary of East Sussex and West Sussex. Starting at Thorney Island on the West Sussex coast and looping inland before finishing near Rye in East Sussex, the trail showcases the full diversity of the Sussex landscape — from coastlines and river valleys to heathland, ridges, and ancient woodland.
For walkers planning self-guided holidays or outdoor adventures, the Sussex Border Path offers a rewarding mix of countryside, heritage, and coast. It links seamlessly with other long-distance routes, including the South Downs Way, Greensand Way, and 1066 Country Walk, making it one of South East England’s most versatile trails.
Thorney Island to the Western Weald
Beginning on the Sussex coast, the path runs inland through the South Downs National Park, passing the chalk ridges near Petersfield and linking to the South Downs Way.
The Weald and Surrey Border
The middle section winds through the Weald, touching the borders of Surrey and Kent. Expect wooded ridges, hidden villages, and stretches of the Greensand Way.
High Weald to Rye
The final section enters the High Weald National Landscape, with its classic ridges, valleys, and historic villages, before finishing at Rye, a medieval port town and gateway to the Sussex marshes.
With its wide arc around Sussex, the path passes many towns and villages perfect for overnight stops, including Midhurst, East Grinstead, Crowborough, Mayfield, Battle, and Rye. Accommodation ranges from B&Bs and pubs-with-rooms to guesthouses and small hotels.
The Sussex Border Path is easily split into weekend or week-long walking holidays, and thanks to strong rail links (notably at East Grinstead, Crowborough, and Rye), it can be tackled in sections for day walks or short breaks.
