- today visitors can descend 9 metres (30 ft) by ladder into one excavated shaft, an unforgettable experience - the only Neolithic flint mine open to visitors in Britain.

A grassy lunar landscape of over 400 shafts, pits, quarries and spoil dumps

Visitors can don a hard hat and descend into one of the shafts to see the radiating galleries at the bottom and the marks made by the antler picks of the original miners.

Try to catch one of the flint-knapping demonstrations (with the knapper in costume wearing only animal skins!).

The small exhibition area illustrates the history of this fascinating site.

If you've had fun on your family day out to Grimes Graves, tell us about it your visit, so other people will know it's a great place to go as well.
