Join Explorers Club for the chance to get up close and personal with code cracking in Dover Castle's wartime tunnels during our spectacular World War II Weekend.

Find out more about the work carried out inside the secret wartime tunnels at Dover Castle by breaking codes and helping to complete a secret mission. When the main event starts, you’ll get access to a special area to get the best view of the action and every member of Explorers Club will get a goodie bag to take home with them.

Explorers Club is only for English Heritage members, and it’s suitable for families with kids between the ages of 7-12. And it’s an add-on experience, so you’ll need to book tickets for the Explorers Club for each member of your family, and a separate ticket for the World War II weekend on our website or on the day.

This event is graded as challenging access due to narrow walkways and steep stairs within the tunnel, so is not suitable for wheelchairs, mobility scooters, or pushchairs.
