Hi, had a great 2 weeks in August in Asturias a couple of years back. We spent the first week camping at La Viorna in Potes which is fantastic, very laid back, nice pool to dip into after your day out, nice small good value restaurant then drove down to the coast. It was a bit of a shock after the tranquility of the mountains. It seemed like the whole of Spain had come to the area for their summer holidays. We stayed at Camping Playa del Troenzo which is right above two fantastic beaches and in a great location. It was however very, very busy but somehow the facilities coped with the amount of people. I saw hardly any other Brits around. Once you get away from the main towns, it quietens down, there are some amazing gravel cycle tracks along the coast where you can find unspoilt beaches in the middle of nowhere. The whole coast is absolutely amazing and unspoilt, however my recommendation is choose your campsite and timing carefully. If I went again, it would not be in August when the Spanish are off.
