Adults: £12

Children: £10 (5-16 Years)

Family: £30 (up to 2 Adults and 2 Children)

Group Discount min 15: Adults £11pp, Children £9pp

Please note: Sometimes being underground there is no WiFi signal for card payment. As payment is at the end we strongly recommend you bring some cash to save embarrassment.

The tour is self guided by personal handsets. This is included in admission price. There is an adult and child tour available which both follow the same route.

There are several films to watch en-route and a dressing up area where you can try on authentic military uniforms and gas masks!

As a rough guide the tour takes about an hour to an hour and a half to complete. However, should you stop to watch all of the included films and take some time out to try on the uniforms then this extends the tour by four hours. Some people find one tour just isn’t enough to take it all in!

Disabled access is limited. Please contact us in advance.
