Just beside the Bar Bruffione (one of the various establishments accessible on the plain), a notice board is visible with a list of the various indications on the destinations that can be reached: the sign initialed "401 - Bivacco P.so Bruffione" indicates our direction to follow. After crossing the bridge over the Caffaro, the mule track begins to climb the slope on the left, in a southerly direction, entering a dense forest, with some panoramic openings, unfortunately created by the cutting of trees made necessary by the presence of the harmful bark beetle. The mule track is really beautiful with a good surface and in the highest part it is also particularly scenic given that the roadway was created by digging deeply into the outcrops of reddish rocks. After about 3 km, you cross a narrow passage "in the trench", a real portal with ancient plants placed on the curved shoulders over the gap. Just beyond the gate everything changes and you enter an incredible natural environment: the "plan di Bruffione", a splendid and wide suspended valley, with grazing herds, ancient huts and a crystalline stream that crosses it. At the beginning of the plain there is a fork: a path to the right, CAI 413, leads directly to the two lakes of Bruffione while the mule track, CAI 414, our route, leads to the homonymous pass (2143m). Go up the Vallone gently along a mule track, of military origins, perfectly maintained, passing alongside the Bruffione and Casinello huts. Here you are immersed in a typically alpine environment with splashes of color donated by a spectacular flora where in the right periods it is possible to see the various blooms of the ferrugineous rhododendron, anemones, lilies and saxifrages as well as some species of wild orchids. For those interested, it should be noted that, making a small detour, it is possible to access a place where on 17 November 1915, 27 soldiers, including infantrymen and Alpine troops, lost their young lives under an avalanche. Unfortunately, it seems that the tragedy was caused by an underestimation by the officers of the suitability of the camp site, a position absolutely not recommended by the local mountaineers. Leaving the last malga, you go up along long but easy walks back to the Bruffione pass and here the view of the basin is spectacular. Once you reach the pass, right on the border between Trentino and Lombardy, at an altitude of 2143 m, at the foot of a pyramid-shaped peak, the small Bruffione bivouac appears, a beautiful stone structure, with bright red doors, with all that which is needed to be able to take shelter in case of bad weather.
