The Lago della Ninfa and Lago Santo are lakes of glacial origin with the typical shape of the Alpine lake, surrounded by dense coniferous woodland.

Lago della Ninfa, easily reached by car just off the road between Pian del Falco and Passo del Lupo, has an unusual history. It used to be lovely enough to deserve its name, which means "The Nymph's Lake", but its water level dropped to the point where it seemed it might even dry up altogether. The authorities stepped in in the early '90s to dredge it and apply a layer of clay to improve water retention, and the situation seems to have improved. The lake is still very attractive from many angles, in winter or summer, but above all in the autumn, when the yellow of the larches contrasts with the green of the other conifers.

Lago Santo is the largest of the Apennine lakes. 500 metres long and 1500 metres in perimeter, its 58 thousand square metres of water lie below Monte Giovo, one of the peaks on the ridge which divides Emilia from Tuscany. It is also accessible by car and this, together with the beauty of its landscape, make this spot one of the favourite destinations for Modena's Sunday trippers during the sommer months. However, Lago Santo is also well worth a visit at other times of year, when the absence of crowds allow its natural beauty to be appreciated to the full.
