Hey SimonC, try taking a walk down the main RASTRO street. There are quite a few ski/snowboard shops on both sides of that street that sell boards, boots, etc... as well as clothes. CLICK HERE FOR CALLE "RIBERA DE CURTIDORES"
I have not yet priced out ski equip. here in Spain but will be doing so this wenter.
I am sure there are tons of other places as well but have yet to takae a good look around.
Saludos, jer...
p.d. Hope you can join us for our next multimadrid trip to Xanad� on Sat., Nov. 29th (as long as you can put up with a few of us Americans -- RE: your signature).
Cheers, I will check it out soon. Not sure if I will be able to make that weekend as I am waiting for my brother to bring my snowboard as i didnt have enough space in cargo to bring it over here with me.
However I will be going there soon after. I love boarding and do it all the time that�s possible. Sierra Nevada is a good place to go, but if you dont want the travelling, then go to the Madrid Mountains and take a day out during the week as it�s not busy!
