Can anyone advise on possibly the best areas in Spain for ski touring and resources/guidebooks for them?

Thanks

Pyrenees ? Lots of guidebooks, mostly in Spanish, one I've used is 'Pirineos en esquis' (https://www.libreriadesnivel.com/libros/pirineos-en-esquis/9788489969490/ ) but see https://www.libreriadesnivel.com/libros/deportes-de-nieve/guias/005002/M/ for a list of ski guides for all regions of Spain (& elsewhere)

Thanks for the tip Doug, shame I can't understand Spanish otherwise I'd have some great resources

Desnivel definitely has a great selection of guides. Massive scope in Aragon, Catalonia and Andorra alone.

Your just not going to find written guides in English (please correct me if I'm wrong) They'll contain topos, maps and with a few key words you can make out most key information. Just a bit of effort.

I've seen books covering both sides of the Pyrenees in French but can't remember seeing anything in English
