In reply to Elsier:
> Has anyone been to either of the destinations above?
Yeah, quite a few times
> Thinking of a trip to either or both next year.
This will need a bit of logitics, prefarably a car. You can get to Gredos by public transport from Madrid, but Picos is a bit complicated.
> What's the best time of year for a trip?
Depends on your goals.
Gredos is known for its ice climbing (

Picos is known for ski touring.
So, if winter activities is what you are looking for, March is usually the best period.
If you are thinking rock climbing, then anywhere between late May (snow can be still present in Picos in June/July) - late October. Avoiding August and late July is always a good idea in Spain, especially Gredos.
> I have a Spanish Guidebook for the Sierra de Gredos, which looks fantastic, but all the info is in Spanish.
Which book do you have? I can translate some bits for you if I have the same one. Or let me know which info you need.
> Most of the climbing seems to be based from a hut (Victory hut). Can anyone tell me how well equipped the hut is, and if it's wardened? Do you need to book in advance and if not are there usually beds available mid week or does it get crowded?
It's wardened whole time in summer months (I guess July-September) and weekends outside these months. They have a place to sleep permanently open, but amenities are very basic, no toilet, I am not sure about stove. You can see photos here:
http://www.grupogredos.com/refugio.html Most of the people on weekends sleep outside anyways, as it's impossible to get a place inside - I am guessing outside of weekends shouldn't be too bad, but it's so small that I don't know if it houses more than 10 people. And there are no beds... If not raining, a lot better to bivvy outside within 200m from the hut.
> Any any other info would be great too.
1. If you are in the Madrid area and feel like you need some slab smearing practice, look at La Pedriza with its immaculate granite slabs that are world-class. Easily reachable in an hour from Madrid by bus, or with a nice hut inside the park.
2. Highlight of Gredos climbing is obviously Los Galayos, but you probably know that. The climbing there is normally all trad, no belay stations on majority of the routes.
3. Gredos has another hut, way better when it comes to amenities, food, toilets, shower etc - called Refugio Elola. It's in the co called Circo de Gredos - it's an area of climbing as well, and you should consider this hut if you want to go ice climbing in winter - as the majority of the ice forms in this valley. This has a lot more places, but the valley is a lot more popular as well - so booking is needed. You get a discount on reciprocal rights if you're part of member federations such as OEAV, SAC etc
4. In Picos you will obviously want to climb Naranjo, you may find other ideas on this page:

Let me know if you need more
