Anyone recommend camp sites in Cantabria/Asturias?

We'll be two families, each with children of 6 and 3, arriving by ferry in Santander towards the latter part of August. We'll be under canvas and, in an ideal world, looking for a quiet site, but one where there are things for the kids to enjoy. Good if in/near the mountains. Bonus if campfires allowed. Thinking rural, but reasonably close to amenities and, say, 30 minutes (ish) from beach. Extra bonus if good walking/rivers/swimming nearby. I know there'll be something out there! More than happy to travel some distance from Santander. Thanks, Alex

In Asturias there's a campsite named Campsite Las Hortensias Cat.1, The place is really nice because it's near the sea, there's also a tennis and kid's play ground.
