Its one of the few places you can see Blue John stone in situ. Our guide was very funny and we had a great time pottering through the caves - seeing the fossils and stones and even some rather nice stalactites.
On Sunday we went to Chatsworth - now unwrapped from its year long face lift and scaffolding. It looked stunning and the Caro sculptures were an interesting addition. We paddled in the cascade, licked ice creams, wandered in the maze and bathed in the sun.
