Route suitable for those using electric bikes (e-mtb) on off-road and trails with very challenging climbs. The starting point is Premana, from here climb to the Laghitt through the Varrone Torrent Valley from the locality Giabbio di Premana, where it is possible to arrive by car and park. The route starts from the parking lot of the Premana craft area, where the mule track begins, following the Varrone stream up the entire valley to Bocchetta di Trona, also called the "iron road" because of the presence of ancient mines. The ride passes by a sign indicating the Casera Vecchia di Varrone hut at 9 km. Among old mountain huts, you pedal on level ground to the left of the Varrone stream and cross the first stone bridge. The road alternates between dirt and concrete-bottomed sections. You arrive at the Giabi farmhouse, where there is a fountain; immediately after passing another stone bridge you return to the left of the stream. From here you begin to climb into a deciduous forest. Valvarrone is best known for the various mountain pastures that you cross along the way: Alpe dei Forni, Vegessa and Casarsa. After passing more hairpin bends, you arrive at Forni di Sopra (m. 1105) where the road in this section is well paved until the hamlet of Vegessa (m. 1200). At the beginning of the hamlet there is a fork in the road; keeping to the left and passing by a cross, you come to a madonnina and a fountain. Passing the last houses there is a picnic area, then continue passing in the vicinity of the Dente Waterfall where the mule track quickly climbs the valley with a few hairpin bends, after which you take the fork on the right to enter a path halfway up the mountainside with wide up and down sections in the forest. From this point the ascent becomes technical, and the trail requires good riding skills. The beech, pine and larch forests are of value, leading to Alpe Artino. From here it is possible to continue up the slope to Malga Alpe Artino for a break, or turn left and continue the ascent on trail. Do not forget to bring water as the trail does not have many landmarks. Almost at the end of the trail, after a series of uphill passages on switchbacks, you will reach the Donkey Lake, then the Laghitt destination, which offers spectacular views up to the Biandino Ridge. From here it is possible to continue to Val Biandino in the direction of Pizzo dei Tre Signori or to Piani delle Betulle following the Cresta di Biandino to Larice Bruciato and Cimone di Margno.
