Watch out for the signs!

The main signage (vertical) consists of "arrow markers" and "location tables" placed on wooden poles at the start of trails and at the most important crossroads; they provide information on locations, indicating name and altitude of the departure point  and distances in hours and minutes of the Destinations, as well as the trail number. 

Horizontal signage, meanwhile, is found along trails, on stones or plants or in the form of stone cairns used to provide continuity information and confirm the route.
