Behind the refuge starts a forestry road (no access allowed) which we leave after a few meters at the sign describing the route to follow. Take the CAI 238 trail on the right, which continues along a narrow but defined trail in a beech forest ending near Casera Nauleni (1637 m) climbing the Colmajer forest, leading directly to the clearing of Casera Nauleni.
Here the loop begins: we climb to the right to reach Forca Nauleni; from the saddle, we continue along the trail that climbs steeply to the ridge of Monte Colmajer and then to the summit at 1858 m. The hike then continues descending the northern side of Colmajer to Forca Grande; from the saddle, still on CAI 238, we reach Forca Piccola (1752 m).
If you want to add some elevation gain, at Forca Piccola (1752 m) you can continue north to reach the summit of Monte Sesilis (1852 m) via a more demanding and exposed trail. The return is by the way of ascent.
At Forca Piccola, therefore, turn right and descend to Casera Colmajer; from here we close the loop along the comfortable forestry road that takes us back to the Casera Nauleni clearing and finally to the Tita Piaz refuge following the same path as the ascent.
