Amazing hole in the ground

France has many caves, here is one that begins with a massive hole in the ground taking you down about 50m, then you go down a further 50m underground.  At the bottom there is an easy walk plus a small boat explores a river section.  Apparently the river eventually breaks ground about 17km downstream.
