I will add from myself that the fragment near Bystra itself is downright dangerous. The path sometimes leads along a slope with a slope of 45 degrees. There is no room for legs, let alone for a bicycle. I was riding a lightly loaded bike and in many places I was afraid that it would end up in the river with all the gear.
After the rain, there must be armageddon on this clay slope.
Interestingly, there is a marked bicycle trail there and it has great potential, but not with such a road preparation.
