This circuit runs around the entire Santa Luzia reservoir. It starts on the dirt road by the dam before following the old road. After crossing the Unhais River on a small pontoon before arriving at Unhais-o-Velho, it follows a road towards Malhada do Rei. The return journey goes around the edge of the reservoir, passing Vidual de Cima, which can be reached along a new and technical section. The route ends by crossing the dam wall, which is always spectacular, after a fun single track.
