A very tough and long cross country route, suitable only for bikers with good endurance and fiscally well prepared. The height gain is very important as the route goes up twice to Santa Orosia hermitage area by 2 different steep 4X4 tracks, and even higher close to Oturia peak.
The best seasons to do this route are spring and autumn, as you could find snow on some parts of the itinerary in wintertime or suffer from a too warm weather in summertime.
