Mountain biking
We came across a chasm that collapsed some time ago, called the Grobias Chasm. This cavity is nothing more than a hole formed in the calcareous soil as a result of water accumulating on the surface and the passage of time.
It's not possible to descend, nor is it even advisable, without preparations and qualified personnel, so I limited myself to taking a few photos and observing from a prudent distance.
