FATMAP difficulty grade
Starting from Biel, the route is pretty steep straight away to pass the first valley.
From Lamboing, it is heading to Mont Sujet but before the top it crosses over to Les prés d'Orvin.
The climb is not technical, just plain fire roads and not too steep! We decided to climb the end of the Chasseral from the north east side, where there is less asphalt roads and more into the woods- more shade.
from the top, we descend in direction of Nods on the usual downhill trail, rooty and rocky but not too steep, just beware of punctures! From Nods, we cross over to join Twannberg and the Macolin, with a cool, flowy descent back home to Biel !
