FATMAP difficulty grade
Starting from Banhs de Tredòs, pedal up the fireroad following the Enduromies signs until the fireroad becomes a singletrail.
That's the start of Pruedo, which is a flattish singletrail with extreme exposures.
Once you get to the top station of a material funicular, go around it.
Here the trail starts getting steeper, but less exposed.
Once you reach the flat meadow, on the left you find the Eth Taro trailhead and on the right the Eth Sanglier trailhead.
At the end of whichecer trail you choose, you can still take the fireroad leading to the trailhead again, or just connect to one of the many mid-accesses to the trails.
