South Downs: Swanborough Hill and Lewes – Walks in England’s National Parks

This hike begins with a traverse of the chalk hills south of Lewes, following the South Downs Way National Trail before descending into the town and finishing with a riverside ramble on the Sussex Ouse Valley Way. It’s a wonderful introduction to the UK’s newest national park and you can expect big views out to the English Channel on a clear day.

From Southease train station, the route crosses the River Ouse and passes the 12th-century Church of St Peter, with its charming round tower. The gentle ascent onto Swanborough Hill’s broad chalk ridge comes next and the views grow with every upwards step. The patchwork farmland, hedgerows and pockets of woodland stretch for miles, only interspersed by villages and the historic town of Lewes, to the northeast.

One of the main attractions to walking here is the magnificent array of wildflowers during the warmer months and the pollinators that their proliferation brings. Colourful butterfly species abound, including the iconic chalkhill blue, while catching a sight of the rare swallowtail butterfly is a real treat.

Descend from the ridge to the east of Castle Hill, passing Kingston Near Lewes and the pretty Ashcombe Windmill, a 21st-century reconstruction of the original post mill, built in 1826. By the time you reach Lewes, you may be in need of a pitstop and there are plenty of cafes and pubs to choose from on and around the High Street. If you have time, It’s worth exploring the town, with its historic buildings and quirky boutiques.

Eventually, you’ll reach the River Ouse, which is your guide for the remainder of the walk, following the Sussex Ouse Valley Way footpath south, back to Southease. It’s a pleasant way to end this enjoyably varied loop.
