In a couple of days, we will be crossing Spain from the hot south to the seemingly also hot north, to Santander, in the province/autonomous region of Cantabria
. It's obviously not a hot (in any sense) touristic destination, but looks like there's a lot to see there. You can follow the Romanic route, the Cheese route (just follow your nose), or just frolic on the beach. I'll keep you (all three of you) informed.
