Karst morphology, Hydrogeology
The Hole of Sovaglia was fully developed from Moltrasio limestone deposited in the deep sea of the Generoso Basin during the Early Jurassic Age. Along with the alpine orogenesis the Generoso massif has also undergone vertical movements and complex bending of sedimentary layers until reaching its current structure. The slow deformation has been accompanied by the formation of faults and breaks, and it is along these fractures that the underground karst network, which makes up part of the Hole of Sovaglia, has developed. In recent underwater explorations, cavers have advanced 500 metres along the Hole to a depth of 61 meters.
Rovio is reached by ascending from Melano, a village situated on the banks of Lake Lugano and midway between exits 51 and 52 of the A2 motorway.
From Piazza di Rovio, follow the lane through the village and go up for 20 minutes to Prato di Pioda. Just above, a clearly-indicated fork in the road leads to the Hole of Sovaglia.
