Discover Our Guide to the 10 Best Walks in the South Downs

Designated as a national park in 2010, the South Downs is Britain's newest national park – although the landscape it protects is as ancient as it is captivating. From the chalky hills of Hampshire to the rugged cliffs of East Sussex, this 675-square-kilometre stretch is a haven for outdoor enthusiasts. With its mix of historical landmarks, tranquil woodlands and expansive views over the countryside and coastline, the South Downs delivers some of the most memorable walks in the country. Whether you're after a scenic stroll or a more challenging trek, here's our guide to the best South Downs walks.

Covering the entire length of the South Downs National Park, the iconic South Downs Way stretches 160 kilometres from the ancient city of Winchester to the towering white cliffs of Eastbourne. The ancient trail traces the high chalk ridges once used by traders and pilgrims and traverses a bucolic landscape of rolling farmland, hidden valleys and picturesque rural villages. Along the way, you'll pass Iron Age hillforts, medieval churches and Neolithic barrows offering glimpses of centuries past. Keep your eyes peeled for nature too, with its diverse habitats home to everything from skylarks and buzzards to roe deer and hares. The trail takes seven to nine days from start to finish and is without doubt one of the best walks in the South Downs. Along the way, check into the ibis Portsmouth Centre, where a comfy signature bed and hearty breakfast will set you up for your next day's hiking.
