Impressive enduro route with almost 100% of singletracks that will allow you to cycle over the incredible Mascún canyon.

The track departs from Rodellar, descends to the Mascún riverbed and then goes up the Andrebot ravine with about 30 minutes of hike-a-bike. After that it takes a gravel road to Losa Mora dolmen and later a singletrack which climbs up to Nasarre and descends to the lovely village of Bara, by the Alcanadre river. From Bara more nice singletracks continue climbing to the uninhabited Miz and the Aire col, where another long trail must be taken heading to Otín and later climbing to a hill overlooking the Mascún canyon. These amazing panoramic views will escort us in the rocky downhill trail till the riverbed, from where there’s only a short climb left to Rodellar.
