The Nala brook leads out of a large valley near Osogna, past huge, high rock walls, down into the region known as the Riviera, where it ends in a wonderful bathing pool in the middle of the picturesque village of Osogna and flows into the Ticino river. After the last ice age, the brook conjured up a fantastically washed-out canyon in the rock. This beauty could not be seen for years because a large rock fall has buried parts of the canyon. But we are lucky, in the last few years nature has slowly and steadily exposed this beauty through rainfalls and snowmelt and we can currently enjoy it in the best condition!
The helicopter picks us up, fully dressed, either directly at the heliport near the Lodrino airfield or directly in Osogna on a meadow. We fly past the rock face of the “Trenta sassi” to the landing site at Alpe In Scign. From there we hike a few minutes downhill to the water intake, which makes it possible for us to climb the canyon in early summer. We marvel at the engineering performance for hydropower and start our canyon ascent.
The canyon begins with little water and leads us in the part called “Nala superiore” under an impressive stone bridge down a 40 meter waterfall, where there is always a water-bearing side stream. Smooth rock slides and beautiful abseils let us start the day. Suddenly it becomes flat and the bridge of the hiking trail into the Valle d’Osogna lines the way. The upper part is already over …
´ “Nala intermedio” – the middle part of the gorge is steeper and technically more demanding. Abseiling points in narrow rocky passages and transfer points at the waterfalls around the corner have to be mastered. Again and again we get a lively shower when crossing the water jet while abseiling. In any case, Nala is technically more difficult than Boggera and includes significantly more abseiling points, the jumps are more technical and the gorge is even longer. The long and technical middle part ends when we reach the edge of the Riviera valley and see the small path of the ascent from “Nala inferiore” on the right. The tour can easily be ended here. We decide on site depending on the group and daily conditions.
Then the Helitour Osogna leads us in the beautiful lower part “Nala inferiore” over many pools and a high 50 meter abseil point to the bathing pool of Osogna, where we end the tour and we can end the gigantic day in the Grotto al Pozzon.
