Alexis, you can snowboard anywhere where you can ski, and that includes locations in Spain as well, like the Pyrenees or Sierra Nevada. From Barcelona, the Pyrenees can be a weekend excursion. And, of course, plenty of other places in Europe; anywhere where the topography allows it. Here’s a list off the top of my head: Norway, Switzerland, Sweden, Austria, Germany, Italy, France, Poland, Bulgaria, Romania, Greece, Slovakia, Slovenia, Serbia, Bosnia-Hercegovina, Croatia, and Spain.

Biarritz vs San Sebastián: Why not check out both? They’re not far from each other.

Yes, you should be able to find a shop where you can rent a surfboard.

I’m planning on going to Norway or France to go snowboarding. What date is snowboarding season? I was planning on going early november.

early november might be too early depending on the location. if you are on a budget, I would recommend the pyrenees in france for a cheaper destination. The alps in France can be very expensive, and I can imagine Norway being quite expensive too although I do not know this from experience. I would plan to go to Bayonne in france next year early august as well for les fetes de bayonne, although I realize this is completly off topic. If you are looking for a mayhem week though, the first week of august is crazy at Bayonne (right next to Biarritz).
