Hi @Tom ,
trail difficulty is generated from the sac scale:
sac scales abov 4 are considered rather difficult:
Hi @poubelle_83 ,
the reason that you can’t get a route in openrouteservice is that the path from Chemin de Navette to your end point is tagged as having a sac scale as demanding_alpine_hiking (sac scale 5). Currently, the highest sac_scale we go up to is alpine_hiking (sac scale 4) as after that the paths can get very demanding and we don’t want to send people unwittingly along a route that needs specialist equipment and training and can be particularly dangerous for those that are not prepared…
It is not possible to activate them during the build process. The information is saved in the graph, but the logic to use them is defined in the flagencoders:

enhancement | feature
on hold :hand:
I'm not sure if this is the right place, but this seems to be some kind of bug.
…
#### Here's what I did
Tried to create a hiking route, but the router doesn't do what I wan't to do (doesn't route me over the mountain, no matter how hard I try).
---
#### Here's what I got
Here is a link, where I think it is obvious what I tried to do:
https://maps.openrouteservice.org/directions?n1=47.40625&n2=11.466336&n3=14&a=47.439917,11.265728,47.452353,11.351624,47.421061,11.428699,47.411187,11.437669,47.410469,11.434568,47.409684,11.434429,47.40959,11.434128,47.376093,11.424408,47.286049,11.4&b=2b&c=0&k1=en-US&k2=km
---
#### Here's what I was expecting
As I said, i'd like to get over the mountain, and don't want to walk an extra tour.
---
#### Here's what I think could be improved
Maybe the tour is too hard for the router, in this case, probably an extra option to enable via ferrata hiking might be helpful.
Best regards
