Start point: the Ferial reservoir dyke.

From the single lane track to the Ferial Services Building, cross the dyke at the head of the weir. The surface is better if you cycle anti-clockwise around the reservoir, passing by the Val de la Fuente del Ferial, the main natural water source to the Ferial (a reservoir whose water mainly comes from the Navarre Irrigation Channel). For the final stretch, the route follows a track parallel to the irrigation channel so precaution needs to be taken.
