Got it, I will have a look into this next week.
And thanks for your comments.

Hello, i only added this shelter to the path to complete the other entries. These are simple stone buildings with no names. They just give you shelter.

I did the trail yesterday and discovered serval passages that have minor climbing elements. Some of them looked like a simple ferratas to me.
Becaus the trail leads down from the Pico Ruivo and some folk will probably use the path, the entry should also warn them.
