Box Hill Circuit

The Box Hill Circuit starts either at Box Hill and Westhumble station, 50 minutes from London Victoria and situated at the base of the hill, or at the National Trust pay-and-display car park at the summit, 35km south of London; no permit is required to walk the circuit itself. The 13km route involves significant elevation change via steep chalk escarpment climbs and descents to the 224m summit, with sustained gradient and slippery chalk underfoot classing it as a hard walk despite its moderate overall distance. The surface is chalk grassland and stepped path, exposed to sun and wind on the open escarpment with woodland shade lower down near the River Mole. Key landmarks include the summit viewpoint made famous by the picnic scene in Jane Austen's Emma, the zig-zag road climbed during the 2012 London Olympics cycling road race, and the stepping stones crossing the River Mole near the base. The summit, roughly 5km from the Westhumble start, makes a natural turn-around point for a shorter there-and-back walk. Water and toilets are available at the National Trust visitor centre and café near the summit, but there are no facilities on the lower slopes. No wilderness shelter is required given the site's popularity and proximity to Dorking and Westhumble, though river levels should be checked before crossing the stepping stones after heavy rain, when a nearby footbridge should be used instead. Most walkers complete the full circuit in four to five hours, encountering chalk grassland rich in butterflies and orchids along the way.
