Park at the car park halfway up the road to the Ghisoni ski resort. The car park is easy to find, as is the start of the trail just opposite, marked with a yellow "I Pozzi" sign.
(S/E) Take the path up on the right and join the GR®20.
(1) Turn left towards Les Pozzi. Reach a fork in the road.
(2) Turn right. The path is not very visible, but one or two cairns indicate the start. The path is not obvious, so don't hesitate to use a GPS, it's easier.
(3) Leave the forest here and continue to follow the cairns through the scrubland to reach Lac de Rina.
(4) From here, the section is not shown on any map. You need to climb to the Col de Pruno, which lies due south: follow the GPX track to reach the col, where you will find a clear trail.
(5) Take a slight left onto a track that descends towards the pozzi.
(6) Leave the trailhead on your left, which you will use on the return journey, and continue straight ahead to reach the northern end of the largest pozzi.
(7) Turn back.
(6) Bend right, ford the stream and reach the Pozzi sheepfolds.
(8) Keep to the left, walk alongside the sheepfolds and continue straight on.
(9) At this point, there is a fork that takes you down to another sheepfold. You can take a short diversions to get there, or avoid it by staying on the path to the left (choice of route). Join the GR®20.
(10) Follow it to the left and find the faint fork in the path you passed uphill.
(2) Continue straight ahead.
(1) Leave the GR®20 and take the path on the right leading directly to the car park (S/E).
