This place was undoubtedly the "highlight" of this stage! Already arriving in the valley, you get the impression of entering another world, literally: the Grigne mountains loom, almost vertical, closing off the valley, the steep road descending towards the stream becomes a small path, the vegetation becomes dense... almost a jungle. finally, you arrive at this spectacular cave, a natural bridge, a very cool place where it is mandatory to stop... also because, immediately after, you climb a very steep staircase!

Beautiful pools with crystal clear water. Trail 15b (Lake Trail) repeatedly crosses the stream, often with fixed chains; waterproof boots are highly recommended, especially in the less warm months.

This oasis of peace is found after a steep descent: the river flows slowly and enters a cave dug by the water. Next to it there are small areas where you can stop, soak your feet and rest before starting the climb.

The Büs de la Noga, also called Grotta dell'Orso, represents the largest cavity in Valsolda. It measures about 50 meters in length, the width varies between 5 and 7 meters, for a maximum height of 7 meters. The bottom, covered with soil, appears to have been moved by the excavations carried out in 1883 by Pompeo Castelfranco. In search of traces of prehistoric man, he instead found a large quantity of bones of the Ursus spelaeus, the cave bear: these finds are now exhibited at the Cantonal Museum of Natural History in Lugano (CH).
