Plenty of Aires on the Algarve, suggest you get the Vicarious book of Aires Spain and Portugal, lots of W@@@ camping too but this is becoming harder, Camping Olhao and camping Fusetta are two campsites we have used in the past I like Olhao nice Portuguese town as is Fusetta, several car parks allow vans to overnight for longish terms but the cops are checking that you are NOT camping which means no kit outside the vehicle, a good Aire at Albufera close to the main bus station so easy to get into town, another Aire at Quarteira which is good,[ the W@@@ was stopped at Quarteira, I was fined there 25 Euros but I had been there for 5 weeks off and on so no big deal , caught about 30 vans that day they did hee hee]the Aire is walking distance to the beach and a good cycle ride or walk along the prom into the main town,strange thing with this Aire is that you have to vacate for one day as the market is held there [Tuesday I think ] but they allow W@@@ on the waste ground next door for the duration of the market and then a mad dash back on to the Aire [by some] to get a prime pitch [ they think] and a hook up,as the market finishes, all this is in the said Vic book I mentioned earlier. have fun, take an umbrella as it rains some .Pictures of the free Aire at Vitoria Gasteiz Spain where we like to spend a few nights en route to Portugal, super old city with a great tram service close to the Aire.
