Dover Castle, Kent - one of the best castles I have visited and so much history.....used through WWII for many different purposes......there are 4 miles of underground tunnels that were used as a hospital during WWII.....built on the White Cliffs of Dover
White Cliffs of Dover. Our tips for 25 fun things to do in England: Get there via Southeastern train from Kings Cross, 2 hours from £40 return. Have a bite at the adorable Pines Garden Tea Room. Make sure to see Deal Castle. Available to explore top to bottom, the castle also links to a cycling path that runs straight to the seaside. Grab a pint at Rack of Ale, Dover's first micro pub. Careful though, this quirky haunt enforces a phones off policy!
