Beautiful and surprising place. It's somewhat hidden if you don't look closely; a very curious cave-like structure opens up in the canyon. Its origin is unclear, but they have plenty of hypotheses! Definitely a must-see if you're passing by this road!

Caves dug into the road from Trespaderne to Oña. A very cool place whose origin is unclear, whether they were used to shelter nomads or as cells for monks.
