Cave tour.

We visited Poole’s cavern in Buxton and had a very interesting guided tour of the caves. Fortunately they allow dogs on the tour and Jak was as good as gold just walking quietly around with the group. 
The caves have an interesting history from the Bronze Age through the Romans to slightly more modern times. 
With an impressive display of stalactites and stalagmites it was a good day out.
