Introbio – Valsassina
An extraordinary nature sight the Troggia waterfall in Introbio Valsassina mentioned by Leonardo da Vinci in his Codex Atlanticus.
The access to the path is closed by gate.
ATTENTION – The mayor of Introbio has renewed the old ordinance of 2003 which “prohibits pedestrian transit in the area along the stream called Troggia leading from via alla Cascata to the waterfall“.
The decision was made for safety reasons due to hydrogeological instability.
Therefore, it is not possible to admire the waterfall from below, but only from the belvedere reachable in half an hour following the signs for Val Biandino from via Alla Cascata.
In Valsasina below Vimognio and Introbio, entering the road to Lecco on the right, one finds the Trosa River which falls from a very high stone into the underground, and there the river ends” (1495; Codex Atlanticus)
Leonardo da Vinci so describes the nature sight of Troggia waterfall in Introbio, where the Troggia creek comes from Lago of Sasso at the foot of Pizzo of Tre Signori and goes on along the Biandino valley till to show us in its thunderous charm in Introbio with a jump of 100 meters. Here it seems to disappear in the small lake as Leonardo says, but Troggia continues its flow becoming the confluent of the Pioverna creek we can admire at the ravine of Bellano.
