We have just left Aguilas, signs erected prohibiting camping also at Playa Calarreona and Playa de la Higeurica. On the way out of Aguilas towards Vera, there is a fuel station, Anibal, which lets you empty cassette, grey water, and fill with water (ask for the key) when you fill with fuel otherwise they charge €2. They also have a camper area where you can stay the night for €7 he also offered to include services €2 and wifi €1 for the same price presumably as we had filled with fuel. There are hot showers, €2, elec 6 amp €3, washer €4 and dryer €3. And areas big enough to wash the motorhome, small charge.
Anyway, over the border into Almeria at Playa Las Palmeras there are a few motor homes us included parked at 37°22′29.57″N 01°38′17.58″W right on the beach! Just got moved on, some people had been there 3 days and they are going back later when the coast is clear.
