In reply to Kemics:
I can definitely unrecommend Esperon De Los Franceses, the cicerone guide wildly understates the route with approximately the same length of scrambling necessary to get off the mountain as there is Climbing on the route. My team got benighted and had to bivvy on a ledge, another team on the meet did it in one go yesterday and didn't finish the walk off until about 2AM having started at 6AM the previous day.
General beta:
Use the water taps at the huts, they are often the only source of water in the area.
Naranjo De Bulnes campsite is good but takes about 45 minutes to drive up to the parking for the nearest big crags. There is a local lad working there at the moment who is a trainee mountain guide called Wan, he is really helpful when it comes to beta on routes and approaches if you are staying there.
If you end up doing something on the Naranjo get hold of the Alberto Boza guide, not cheap but photo topos of each pitch are really helpful.
The 1:25K adrados maps seem to be the most well favoured, either available on Amazon or in the local outdoor shops in Arenas.
If you have any specific beta questions about where to eat and where to park please feel free to drop me a message and I'll see if I can help.
