Just above the San Adrián tunnel. You have to be a little careful on the last climb.

In the tunnel of the same name stands this small chapel, a beauty in itself and for its surroundings.

Ample space to park the vehicle. Although it is wide, it is appreciated that people park their vehicles close to each other because at certain times the parking lot collapses.
