From the Calvi refuge, the signs lead toward the
Sesis Pass (CAI 132). At the pass, taking the path to the left, the trail descends into the
Fleons Valley at length (CAI 140) reaching the
Casera Fleons di Sopra from which the trail, first on a path, becomes an obvious paved mule track. Descending to an elevation of 1570m, near
Casera Fleons di Sotto, Sent. 403 proceeds slightly downhill, crosses a stream and joins a little further on the mule track that reaches uphill the pasture of the diruta
Casera Sissanis di Sotto (CAI 142).
Keeping the same direction, go up the Sissanis valley to the Sella Sissanis pass, in view of Lake Pera and Creta di Bordaglia. Proceeding frontally on CAI 142a one goes by gravels below the walls of Creta di Bordaglia reaching a small saddle with remains of trenches. Continuing straight on, slightly downhill, the 403 leads to Giramondo Pass from which you descend abruptly into the Rio Volaia valley, in Austrian territory. After a steep grassy shovel, the trail drives in a long traverse to the right through a forest and a wolverine before coming out into the alpine pasture ofAlpe di Volaia. Toward the right the service road of the Volaia hut climbs in twists and turns toward the pass of the same name; it will be possible to use the many shortcuts between switchbacks or faithfully follow the dirt track. With a final, steeper section, you will reach the basin of the beautiful Volaia Lake and just beyond, to the right, the Italian-Austrian border. Descending near the Lambertenghi-Romanin refuge and continuing for a few minutes further downhill, at an altitude of 1935 you meet the fork to the left that leads to the Spinotti equipped trail (tables). The trail begins with a wooden ladder ladder and continues along leaning walls equipped with safety cables up the wide rocky ridge, trending to the east. A final steep section leads to an area of meadows and limestone overlooking the valley of the village of Collina. Keeping the same direction, on CAI route 145, you will reach the Marinelli refuge, ignoring the tracks that from right and left affect the path to Mount Coglians.
