The North Downs Way crosses the river at Box Hill via seventeen hexagonal stepping stones, which are frequently submerged after heavy rainfall. The current stones were dedicated in September 1946 by the then Prime Minister Clement Attlee, replacing those destroyed during the Second World War as an anti-invasion measure. The location is popular with anglers and families, but swimming is strongly discouraged as the water is polluted in places. The stones give their name to the pub in the nearby village of Westhumble.
