A circuit that starts and finishes at the “Centro Pro Natura del Lucomagno” in Acquacalda. Just under 20 km… but with high content! The whole route unwinds on mule tracks and single trails. Envelopped by an enchanting nature, you ride up the path, along the Brenno river, towards the Lukmanier Pass. Once reached the pass, proceed on a comfortable dirt road that runs alongside the artificial lake of Santa Maria. After a couple of kilometers the strenuous climb to the Passo dell’Uomo begins, on a very bumpy mule track; after a few hundred meters you are forced to get off the bike and push it for 15-20 minutes, almost until the pass. From there, continue on a dirt road to the junction for the Passo del Sole, which can be reached uphill on a demanding single trail: for the most trained and endowed with good technique, the climb is 100% cycleable. The view at the Passo del Sole is extraordinary: a short break and you are ready for the long descent on a single trail. A real high and a lot of adrenaline for those who dare! When you reach the “monte di Lareccio”(alp), after a short climb, take the fun single trail in the “Selva Secca”, leading back to the starting point.
