Blue John Cavern Blue John Cavern

The Blue John Cavern in the Peak District is a series of caverns considered to be the finest range in Great Britain.

Our Cavern Tours are of immense educational interest showing clearly how the caverns are formed in limestone strata and how the limestone itself had much earlier been formed by the deposits on the floors of great oceans which have long since receded, as the fossilised remains of marine animals now show.
