From the little lakes of S. Leonardo cross the Torrent Vermigliana and continue downhill on its right side. Led by the fascinating medieval tower of the Castle of Ossana, climb through the village, go past the church of S. Vigilio and take the road to the beautiful Valpiana. By the aedicula of S. Antonio turn to the right and follow the indications to Malga “Dal Doss”. 300 m before the Malga, just before a switchback, leave the forest track and turn to the right onto a difficult trail for about 100 m, which takes you to the forest road of Barco. Go uphill its length and take the sometime marshy trail that crosses the Rio Barco – through a little wooden bridge – for 700 m. Turn right and get to the forest track Palù-Barco: from here on a long descent leads to the Masi di Volpaia, after passing past the junction Masi di Palù and Solcar. Proceed on the road alongside the meadows and return to the little lakes of Vermiglio.
