The vicinity around Robiei is home to ibex, so keep your eyes open on the ridge and enjoy a breather before the steep and stony descent towards the Lago Nero and Lago Bianco. Why is the Lago Nero so dark and the Lago Bianco so light? The former is a natural lake with a natural spring, so the water is somewhat darker, while the latter is a manmade reservoir mainly created to store meltwater, which contains light-coloured minerals.
Day three finds you entering Italy along the foot of the Basodino glacier and overnighting at the Capanna Maria Luisa refuge. Note the broad plateaus with turquoise lakes and polished glacier rock. The long ascent on day four takes you to the highest point of the tour at alt 2700 m. and past the Lago Cavagnöö and Lago Sfundau to the Capanna Cristallina refuge. The last leg of the tour again involves a long hike, this time via the Lago Naret back to Fusio.
This 60 km trek is an extension of the Via Alta Vallemaggia which was created in 2009 and links Cardada-Cimetta with Fusio. Click here for details and technical information about the tour.
