Fan Bay Deep Shelter

Fan Bay Deep Tunnel - Image Richard Crowhurst CorvidaeAfter a period of conservation and renovation, The National Trust has opened Fan Bay Deep Shelter to the public.

These abandoned and forgotten tunnels within the White Cliffs of Dover remind us of a time past.

They were constructed in 1940-1941 as accommodation for the gun battery above.

Follow your Guide deep into the cliffs - in fact, 70 feet underground! 125 steps take you into the shelter and back out again. The tunnels are unlit so the only light will come from head torches. Hard hats are also provided. We advise that you check the visitor information on the White Cliffs of Dover website.

The tour also includes a chance to see the First World War Sound Mirrors up close and find out more about them.


Please check the opening times via the National Trust website.

Tickets are sold at the Fan Bay tunnel entrance on a first-come, first-served basis.

The tunnels are located 1.5 miles from the National Trust White Cliffs Visitor Centre - you can check availability before walking along the cliffs to the entrance.

  • Tours leave every 30 minutes from 11am to 3.30pm. The last tour leaves at 3pm.
  • Maximum of 12 people on each tour - age restriction of 12 years.
  • The National Trust is unable to accept payments by card, due to the remote location.
  • Please wear sensible shoes.
  • The nearest toilet and catering facilities are located at South Foreland Lighthouse - 0.5 miles away.
