Arrive in good time
Arrive 30 minutes before your tour time. Everyone passes through a metal detector, bags are screened, and every visitor aged 18 and over must show valid government-issued photo ID, such as a passport or driving licence.
Pack light
Leave large bags behind. Video is not permitted on the tour, and your guide will tell you where you may take photographs.
Visiting with children
The tour welcomes guests aged 5 and over: children under 5 cannot join any tour, and visitors aged 5 to 17 must be with an adult. Tours run rain or shine, so dress for the weather.
