As you might expect with so much water flowing down from the mountain tops, the Pyrénées has a wide range of cave complexes.

They are mainly concentrated in the lower reaches of the Pyrénées where one can find some real subterranean masterpieces!

They provide an excellent option for rainy days as the temperature will usually be around 13 degrees C underground, whatever the weather outside!
