Nerds, tube nerds... prepare to get shaken and stirred with two rare chances to tour disused tunnels, with one offering access to areas used as locations in the James Bond film Skyfall.
That tour will take you through parts of Charing Cross that were closed in 1999 stretching underneath Trafalgar Square. The tunnels are now used largely for filming movies and TV shows, with Daniel Craig chasing Javier Bardem around an area slyly disguised as Temple Station in Skyfall. The recent Paddington film was shot there too. Tours take place in June and July with tickets released on 17 April at £25 (£20 concessions).
The second tour in Clapham South is even more exciting, as it includes a visit to the deep level shelter next to the main tunnels which was used in the Second World War during air raids. This one represents an extremely rare opportunity to get to parts of the Underground not normally open to the public. Tours take place in October with tickets released on 17 April at £30 (£25 concessions).
Both tours are run by Londonist media partners the London Transport Museum.
