If you want to stay close to the life of Albufeira, but in a calm area with a good beach, Oura is a very interesting option, at walking distance (well... for good walkers!).
Good facilities and a small park that works well out of peak season.
Praya De Oura is a hive of activity on a fine, sunny day. Unfortunately the day we went there and spent the longest time on the beach, I forgot my camera!!!
From the beach here, you can go for a banana boat ride, try your hand in paraascending, jet skiing or just mess about in the water.
Here you see Mary adorning the golden sandy beach. Unfortunately, this was our final day here, and the weather had changed overnight, so there were no water activities. the lifeguards were busy keeping people out of the sea!
