Gently climb the military road. The trail is pretty easy. After a few hundred meters you see on your right the trail that goes to the upper lake and the Tesina Pass (from where you will come back).
Proceed straight on the bumby military road you then reach a valley with a small lake (2,156 m).
Walk bordering the lake on the right side, the trail is now less bumpy and it gently unfolds towards the south. Further on, after leaving behind a semicircle shaped stretch near sheepbacks, the trail continues upwards, with many easy walking serpentines that lead to the Sant’Anna hill (2,308 m).
A sign and two steel crosses indicate the exact location. Facing the French side, you can see the rugged valley whose road leads to the ski station Isola 2000. Proceed on a slight climb and you arrive at Tallone’s mountain hut (2,335 m).
The trail continues on a smooth grassy valley, then on a mule track and on a zigzag offering a good view of the Sant’Anna lakes.
Going around a rocky ridge, the mule track loses some height and leads to a semicircle path that ends on a small wooden bridge where a steel rope helps safely cover a somewhat unstable stretch.
Few meters later you go around a second ridge leading to a rocky and lonely valley that ends with the climb to the Lausfer hill (2,430 m). It is very likely to see peaceful ibexes roaming in the barracks on your left. As soon as you appear at the French side you see three wonderful lakes (Lausfer inferior) that make the place really pleasant.
The trail continues descending on the right of the lakes and goes through a grassy hill, where a few forts and barracks remains are located. From the hill you admire the fourth lake (Lausfer superior), the biggest of the four lakes, hidden and nestled in a rugged environment under the Testa Auta of the Lausfer (2,587 m).
The downward path touches this lake on the left side, goes through some (easy to cross) rocks, and continues uphill until reaching a first rise. Continuing on the grassy valley you reach a second rise. From this point onwards the path becomes flat but unstable. Proceed with caution, given the steepness of the ridge, and you get to the Saboulè (2,460 m).
The rocky environment is severe and typical of high mountain. Take a sharp right turn and get back on the Italian side. The path continues along a small barrack on the side, and then on a long semicircle under the rocky slopes of the Testa of the Lausfer. In this stretch you can still find snowfields until early July.
In the valley on your left side there are few small lakes. Approaching the Tesina Pass (2,400 m) the trail, now a mule track, goes near some mighty rocks and precipices (be very careful especially in case of presence of snow), and after a few sharp bends comes out on a panoramic pass.
You are now back in the Sant’Anna valley and you easily descend towards the last five lakes concluding this wonderful circular path, with the satisfaction of having completed one of the most gratifying excursions of the Maritime Alps.
