Anavalos beach
A pebble beach on the limits of the prefectures Argolis and Arcadia below the Monastery of Osia Makrina. You descend a dirt road to get there and there is a parking space on the beach. When you swim, due to the waters of the Anavalos spring, the water is warm in some places and cold in others. But this is a pleasant and peaceful beach anyway. Towards Anavalos there are secluded spots where you can either sunbathe or dive. Anavalos can be seen in the distance.

One more small beach with rocks next to Anavalos beach. On the map below it is marked as Agios Georgios beach by the homonymous church located above.
Below is a map with the location.
