Lewes to Southease

This 9.7 km circuit follows the River Ouse south from the historic county town of Lewes into quieter Sussex countryside, mixing riverside paths with gentle farmland sections and views across the Ouse valley toward the South Downs. The route avoids the steep chalk ridges typical of the area, instead offering a more relaxed walk through the river's flat floodplain before climbing gently through fields on the return. With 268 metres of elevation gain spread across gentle gradients, the walking is moderately physical without being demanding. The river provides a constant companion through the first half.

This dog friendly walk provides pleasant variety for dogs who enjoy riverside environments. The Ouse offers water access at several points for drinking and paddling, and the mixed terrain of riverbank, meadow and farmland path provides varied scenting throughout. Off-lead potential is moderate on the quieter riverside stretches, though leads are needed through farmland where livestock is moderately likely. The gentle terrain suits dogs of most fitness levels, and the proximity to Lewes means good refreshment options at both ends. Southease's small church and railway station make an attractive turnaround point.
