Chislehurst Caves is a series of man-made tunnels and caverns covering some 22 miles (35.4 km) in the London Borough of Bromley. The caves served as munitions storage for the Woolwich Arsenal during the 1914-18 war and are now open as a tourist attraction and education centre with a gift shop and café. Entrance is by guided tour only, lasting 45 to 50 minutes, though the caves have natural uneven floor surfaces which present difficulty for pushchair and wheelchair users.
It is 2 minutes' walk from Chislehurst rail station.
