I am at present in a delightful site in Portugal. Ok! It is not on the coast, it is inland between the Algarve and Lisbon. All good from my point of view. Not noisy, nice pool, plenty of space and very good prices.. It is called Monte Naturista; its on Google.
All year round and with, I am told, good weather.
Access good for 32' on one mile of non-asphalt surface, typical for the area. Pool, Free WiFi, Meals etc but no shop. Our first visit but will certainly return. Temp. at moment 32c daytime and cool in the evenings, so good for sleep. Plenty of shade and some level ground.
TomTom co-ordinates will bring you to the gate.
Hope this helps.... Alan
