Almost everything you can expect to see when you visit Dover Castle.
The Castle is within walking distance of central Dover but many people drive in.
You do climb a few steps but the walk only takes 15-20 minutes.
The newly re-opened secret wartime tunnels exhibition is a must see as is the walk through the WWII underground hospital. The Great Tower of Henry II in the Inner Bailey is very cool, don’t miss the medieval tunnels as well. An awesome spot to spend a morning or afternoon.
