Duration in hours
Distance in km
Suggested period

Varied exploratory circuit with an interesting variant.

Signage: 756. Passo San Udalrico - Tour

The Passo Udalrico crosses from Drena over into the Valle di Cavedine. This you reach after just over four kilometres on minor roads with little traffic. From the pass, turn left along a road to Chiesetta di Maria Ausiliatrice, passing a lovely set of stations of the cross. Then, a few bends further on, take a forest track and enter the woods. You then coast easily downhill until, after about 9 km, you have the choice of descending via a short, easy trail to the road that leads back towards Drena, or to tackle the appealing San Siro variant. The route back to Drena involves ups and downs on different surfaces and paths, all the time enjoying a beautiful view of Lago di Cavedine and the landscape of the Marocche. Right at the end you climb up the road to Drena Castle.

Variants: 756a. Variante San Siro

Safety guidelines

ITRS - International Trail Rating System

The ITRS is an objective way to assess trails and routes from a biker’s perspective, evaluating four aspects:

  • Technical Difficulty: riding skill level needed
  • Endurance: combined effect of length, uphill and downhill
  • Wilderness: amount of planning required based on mobile phone reception, rescue options, water supply and wildlife
  • Exposure: consequences of a fall

Discover more about the ITRS system and check the classification of this tour in the photo gallery.

Punto di partenza
Parking place at Drena Castle

The route starts near to Drena castle, in the nearby car park. Initially you will not find the route directions (number 755). First, take the provincial road towards the beautiful village of Drena, leaving the castle behind you. After about 400 meters, cross the road to take the initially steep - Via Rovereto on your left. Follow this quiet internal lane, which leads you to proceed parallel to the provincial road below. After crossing the locality of Naroncol you will again meet the provincial road. Cross this, and after a few hundred metres, turn right - dropping down into Luch. Still riding on asphalt, at the next junction (now led by the signs) - turn left / northwards to ride through the crop fields of the Cavedine valley. After a short gravel track taking you to a crossroads, keep right towards the centre of Masi di Vigo. And before reaching the built-up area turn left again heading north, until you once again meet the provincial road at Passo San Udalrico.

Continue right on the main road, and after around 200 meters turn left to climb up Via Coste, reaching a village of the same name. This road is characterised by a very Italian sight - the stations of the cross, leading you up to a small church. Here continue straight ahead, following the road to discover the route signage which indicates you to continue on the forest road. Ride downhill on the pleasant, undulating path, which is stable and quite flowing. At the end of the forest, continue straight until you reach the stop sign where you must keep left on Via Trebi. Next you will find yourself in an archaeological area which you must leave on your, following the main road. If you want to lengthen your adventure, you could always follow the directions of route 753, which then rejoins this. Otherwise, continuing straight on the road, you will shortly begin to descend, with Lake Cavedine and the Sarca valley below you.

Guided by the signposts - take the second fork that you shall meet on your left, interrupting the descent to continue on a slightly uphill, gravel road.

At the end of the road continue straight to face the last downhill stretch, the most technical part of the whole route. Having successfully tackled this section, you shall once again meet the provincial road to Cavedine. Here turn left, going uphill for about a kilometre over a couple of divine hairpin bends to once again reach your start point.
