In Ontón the camino climbs a set of stairs to bring you back up to the level of the N-634, at a point where the road curves sharply and arrows point in two distinct directions.
Option 1: Along N-634 through Mioño & tunnel- 7.1
To follow the new route, simply follow the bend in the road and keep on it as it twists and turns. It will cross under and over the A-8 several times before arriving in Mioño.
Option 2: The Old Camino - 14.8
The old camino route crossed over the N-634 at this bend, and followed the CA-523 in the direction of Baltezana. The way is still well marked but has been largely abandoned in favor of a newly marked route along the N-634.
