Before booking a tour, please bear in mind that the tunnel is dark, damp and dirty inside. You will need to wear wellies or sturdy walking shoes or boots as your feet may get dirty and wet and the tunnel floor is uneven in places. In addition, please make sure you read and understand the Terms and Conditions at the bottom of this page before booking your tour.

* Children must be at least 1.1 metres in height and physically capable of ascending and descending the staircases by themselves unaided.
