Fiemme Old Railway
From Cavalese towards Carano and than continue along Aguai; at Passo San Lugano take the former railway line trail with the long descent to Ora (20 km), passing inside some tunnels. The trail is in part dirt road and thus requires some attention. In Ora there is a stop off at Bicigrill where you can have something to eat or to reload your bike battery, than the tour goes on to lake Caldaro. Return on the same way.
