Good to stop and admire the view, be careful not there are people with the venta in summer. Also watch out for the cows which are wild and can be unpredictable.

It is one of the bridges on the route. It is preferable to use a flashlight inside, since there is not good lighting. On some occasions there are water leaks, which gives it a more interesting point when crossing it.

Recommended to bring lights. The longest tunnel, despite having light sensors, often does not work. Be careful that there were landslides on the shore.

The Col d'Ibardin is located on the Franco-Spanish border, in the Pyrenees. It separates the department of Pyrénées-Atlantiques, in France, from the foral community of Navarre, in Spain.
