The Mole, passing the Grade I Church in Stoke D'Abernon, Cobham Mill at Grade II and Painshill Park and the Wey, passing Silvermere Golf Course and the Brooklands circuit, hotel and retail park, cut through the borough from south to north reaching the River Thames which denotes the northern border, stretching from Weybridge to Thames Ditton apart from inclusion of inhabited islands such as Wheatley's Ait. The Wey and Mole have sources beyond gentle valleys which cut through the high North Downs to the south.
