Length: 27km (16m) or 20km (13m)
Toughness: 7 / 10
Transport: Take the 9:15 from London Bridge (9:29 East Croydon) arriving in Balcombe at 9:55. 4 trains / hour return from Horsham to either London Bridge or London Victoria.
Either buy a day return to Balcombe and sweet-talk the station master in Horsham to let you through the barrier or buy a single from Horsham to Three Bridges for a return to London Bridge, or buy a day return to Horsham (Balcombe does not have barriers) and potentially explain to the conductor that you want to walk from Balcombe to Horsham.
In the morning this walk follows the Balcombe circular before heading off towards the west and St Leonards Forest, the watershed between the Thames and the Channel and the source of the river Arun. There, you have a choice of either going straight towards Horsham station or following a southward loop to enter Horsham centre passing its church and explore this pretty market town with its many pubs and restaurants. A mixed walk of woodlands, water features and farm land.
