We woke out late and, after having lunch, we took the car and went
to Patones.
First of all, we went to a place near Patones de Abajo commonly
used by many cavers to improve their abilities. There, we saw a ditch
which concluded in a large waterfall.
Then, we went to Pontón de la Oliva to look for the exit of the
Cueva del Reguerillo. We found it!
And then we got into the car again and went to the main entrance of
the Reguerillo, with some light and we visited it (from the beginning to the lake).
