An Hiking tour of about 15 km, the Alta variant of the Sentiero del Viandante, along a steep path that connects Lierna to Ortanella and from there to Varenna.
From the thick Val Brentalone, on a steep path that crosses the cliff of Zucco della Pecora, you reach the cross of Brentalone, 650 m above sea level.
Continue to Alpe di Mezzedo, with its ancient "Giazzera" and a breathtaking view of the center of the lake that is hard to forget. From there to Ortanella, the highest point of the Sentiero del Viandante (952 m asl) with its ancient church of S. Pietro. After a well-deserved lunch break, the journey starts again on the lake side, descending the ridge that, between the valley of the Esino stream and the coast of the lake, reaches Vezio and then Varenna among views of rare beauty.
