From Bordei ascend about 5 minutes on the small road until in the bend at 780 m the hiking trail branches off right into Val di Bordei, crossing shortly afterwards the rushing creek on a wooden bridge at P. 789. The trail leads around some boulders ascending gently through the fairly wide and shady valley floor until at ca. 880 m it crosses the creek again to reach the other side of the valley. Now the valley narrows, and the trail ascends more steeply southward, traverses a tributary creek at around 1060 m and zigzags up through brushwood to the small hunter shed (ca. 1380 m). It is mostly open and offers welcome shelter in case of a sudden weather change. However, as it is humid and grubby inside, it is not inviting enough for a longer stay. Afterwards the trail crosses the main creek yet again. From P. 1433 on the trail continues on a ridge interspersed with bushes via P. 1594. At an altitude of about 1800 m Val di Bordei widens to become a high plateau, from whose eastern edge one reaches Bocchetta di Valle (1948 m) in a wide arc. The spectacular view down to Lago Maggiore and further on to the Apennine range encourages taking a long break in the wide saddle. From Bocchetta di Valle many trails lead up to the mighty summit cross of Gridone. They all reach P. 1999. An interesting route is across some small rocky ledges and north-westward to reach the wide ridge at an altitude of ca. 2130 m. The last metres to the Gridone summit (2188 m) are unproblematic on schrofen, slightly on the Italian side of the ridge.

The descent from the summit to Capanna Al Legn follows the ridge until ca. 2130 m on the route of the ascent, then it continues on the ridge until shortly after the rocky outcrop at P. 2138, where you can descend to Bocchetta di Valle on a distinct rib. Following the markings hike eastward on a faint path to reach Rifugio Al Legn (1785 m) in a few minutes. It is located on a splendid terrace high above Lago Maggiore.
