South Downs National Park essentials

Address: South Downs, Hampshire, West Sussex and East Sussex, England

The park covers about 1,627 square kilometres and stretches roughly from Winchester in the west to Eastbourne in the east, taking in the chalk South Downs and a substantial part of the western Weald. The chalk ridge forms the iconic white cliffs on the coast such as the Seven Sisters and Beachy Head, while the western Weald is a contrasting landscape of wooded sandstone and clay hills.

The South Downs Way is the National Trail that spans the whole length of the park, and the area contains a scattering of historic towns and country estates as well as farmland and heath. The South Downs National Park Authority administers the park, balancing landscape protection with public access and the needs of local communities; the authority took on full planning powers in 2011.

Designation as a national park is relatively recent, and the area was also recognised for its low light pollution when it received International Dark Sky Reserve status in 2016, making it a popular place for stargazing as well as daytime walking.

  • South Downs Way: The long-distance National Trail runs the length of the park and offers multi-day or section walks across the chalk ridge with waymarked paths and varied countryside.
  • Seven Sisters and Beachy Head views: Dramatic chalk sea cliffs and headlands on the south coast provide striking cliff-top walks and panoramic views over the English Channel.
  • Arundel and its town: The historic town of Arundel and its castle sit within the park boundary and provide a mix of medieval architecture and riverside streets to explore.
  • Western Weald woodlands and parkland: The western Weald offers a quieter, more wooded contrast to the downs with rolling vales, ancient woodland and country estates.
  • Sheffield Park and Garden: A designed landscape and lake-filled gardens that illustrate the parkland and horticultural heritage found within the national park.
Things to Do
When to Go

Best Time to Visit South Downs National Park#

The South Downs is pleasant year-round but seasons suit different activities: spring and early summer for wildflowers, summer for coastal walking, and autumn for quieter long-distance routes.

Spring (best)
March - May · 2°C - 16°C (36°F - 61°F)
Spring brings fresh green downland, wildflowers and newborn lambs, making it an excellent time for day walks before the summer crowds arrive.
Summer (busy)
June - August · 9°C - 21°C (48°F - 70°F)
Warmer, generally drier weather favors coastal cliff walks and longer days, but popular sites and car parks can be crowded on fine weekends.
Autumn (good for walking)
September - November · 4°C - 18°C (39°F - 64°F)
Autumn offers cooler, crisp days and clear visibility for long views; rainfall rises later in the season so plan for wet conditions on exposed ridges.

Tips for Visiting South Downs National Park#

  • The park covers a very large area - decide which section you want to explore and base yourself in a nearby town or village.
  • Weather can change quickly on the exposed downs so bring layers, a waterproof and good walking footwear.
  • Follow public footpaths and waymarks and carry an Ordnance Survey map or GPS route for remote stretches where signage is sparse.
  • If you want dark-sky conditions for stargazing, check local access and avoid lighting that could disturb livestock or residents.
  • Respect grazing livestock and farmland by leaving gates as you find them and taking all litter home.
