The shortcut on this app once you pass Islares is an extreme route that is quite dangerous. It is an extremely difficult route than should come with warnings. The yellow arrows actually turn into black arrows. This section should only be done by expert hikers only!!!!! I did this section last year and it should NEVER have been listed as a viable camino route. A rescue occurred yesterday of a 31 year old Ametican pilgrim. I have completed the Northern route twice and this is not a good option for the average pilgrim. This should be definetly be removed from the app. It is dangerous!
