From the hamlet of boys (mountain station cable car) with the mountain bike better take the lower path, which is signposted with Moosalp. After Wolftole the route could even be mobile. From the Augstbordstafel climb to the Augstbordpass.
The upper routes are exposed, extremely rough and lead through block fields. I myself went the top route. I would not take these - neither in one direction nor the other.
The descent to pits and further down is sometimes quite demanding, but full of enjoyment.
