This circuit aims to promote the natural and farming resources of the area surrounding the springs of the Alviela Olhos de Água. It starts by the MTB centre and follows the river on the Alviela aqueduct before crossing the Ferreira bridge and continuing towards Raposeira. It passes through an area of crop fields before arriving in Monsanto, where some karst formations typical of this mountainous region can be seen. It returns via the Olhos de Água river beach.
