Park at the Col de Vizzavona.
(S) From the car park, take the path northwards to the start of the circular Boucle des Cascades des Anglais to reach the fort. Go behind the fort and take the path on the left.
(1) At the crossroads, turn left (signposted "relay stopover lodge") and continue following the red and white markings. (On the right, the path leads to the beautiful Cascade des Anglais waterfall, where you can stop on your way back).
(2) After a good kilometre, at the crossroads, pay close attention, as you need to leave the marked trail and turn left to find the Bergeries de Porteto trail. There are no markings, so look out for the cairns. A few metres further up, a huge tree trunk blocks the path. Step over it and you will find the sheepfolds just above.
(3) At the sheepfolds, 1 metre below, there is a spring.
Return via the same path to get back to the car park (S/E).
