Britain’s oldest road, the Ridgeway, follows the same route over high ground used by herdsmen and travellers since prehistoric times.

Explore a remarkably isolated and unspoilt corner of Southern England through some of its most ancient landscapes, finishing by the 5000-year old Avebury Standing Stones, a UNESCO World Heritage site.
