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 passing the Alviela estate and running through a large area of farm fields, mainly planted with cereal crops. It continues as far as the cycle track, which it uses for the return journey via the Olhos D’Água river beach.
