My avatar is of a beach just north of Aguilas, you'll find it listed in CamperContact but the more famous beaches south of Aguilas I found singularly unimpressive when we visited them last May or June - packed with people and not very clean. Our guide books raved about the Cuatro Calas but they are a very mixed bunch. The one nearest the campsite does have nice sheltered swimming though, but perhaps not at this time of the year!
Cycled to calabardina, about another 30 motorhomes there also, but some space by the water. Many are parked in little areas back from the sea.
I was told the Czech's use the sheltered swimming spot every day to wash in
BTW @DBK we are staying at Bella Vista after reading your blog and have found it the friendliest site we have ever stayed on. Many thanks.
