On Google Earth, the mountain looks bald. Lower down it bristles with trees, but up here it looks like the bald pate of a man trying to hide his age: covered with fine white hairs brushed parallel. There are dozens of these white lines. Animal tracks?
On Catalan maps there is a real path in there somewhere but none of the lines on Google Earth looks important enough to be a path with a name. So, does the Camí de Aulà really exist? I email Fornet, the nearest hostel, but the reply is vague. I look on Wikiloc. Nobody has uploaded a record of having walked it. I ask in the local Facebook walking group. No luck there either. There’s nothing to do but take the risk.
