Fremamorta Pass

From Pian della Casa del Re (1735 m), the trail follows the same route as the "Il Colle di Ciriegia" itinerary {->16} until the second turnoff on the right (signaled), for the intermediate Lake Fremamorta and Colle di Fremamorta (ignore the first turnoff to the right, also for the intermediate Lake Fremamorta).
The route abandons the mule track for Colle di Ciriegia and climbs to the right, in tight, steep switchbacks through a thicket of green alders. Further uphill, the trail rejoins the old mule track, which rises up to the top of a ridge. Just at the crest of the ridge, there is a turnoff. The route abandons the mule track for intermediate Lake Fremamorta and turns left, on the narrow path that leads directly to Colle di Fremamorta.
The trail, fairly steep, rises over the crest of the ridge, then veers slightly to the right, entering a small detritic valley. It skirts a large boulder in the middle of the valley and then climbs a steep slope with a very long series of tight elbow turns. After an abrupt turn to the right, the trail joins the ex military mule track from the Fremamorta Lakes.
The route follows the mule track to the left and climbs up the slope with a series of long switchbacks until coming to a well-marked fork: the path on the right leads to the western Colle di Fremamorta and the Alpine Corps barracks of the same name, while the trail to the left leads to the eastern Colle di Fremamorta (or simply Colle di Fremamorta, 2616 m, 2 hours and 45 minutes from Pian della Casa), where it reaches the pass.
