South Downs Way

South Downs Way is a UK National Trail long-distance route across the South Downs in southern England, running for about 160 km between Winchester (Hampshire) and Eastbourne (East Sussex). It’s routed as a multi-day hike with an elevation change cited at about 4,150 m, and its mapped length in this dataset is 175.67 km.

Most of the way stays on chalk downland: the route follows old tracks and droveways along the ridge and escarpment, with sections that are described as undulating rather than steep continuous climbing. Expect a sustained upland feel, with frequent high-ground walking and periodic drops/returns when the route reaches towns and access points.

Waymarking is a core part of route-keeping: it’s signed as a National Trail using the acorn symbol, and the trail is described as generally well signed. The route was approved as a National Trail in March 1963 and opened in July 1972; it was also identified as the UK’s first long-distance bridleway.

Route character includes both inland downs and the final coastal finish. The trail’s east end is linked with the Seven Sisters/Beachy Head chalk cliffs before descending to Eastbourne for the finish.

The route runs within the South Downs National Park and is described as having its easternmost section on the high chalk cliffs of the Seven Sisters. Historically and geographically, it’s associated with long-established path networks that predate the modern trail.

For planning, typical walking time is given as about 7–9 days on foot (and 2–4 days to cycle). Accommodation and overnight options are common along the route, supporting day-by-day variations rather than one fixed itinerary.
