The beach is beautiful and easily accessible, there is a direct bus to the beaches from the center of Athens. The beach part belonging to the Bolivar bar is paid/6€ on weekdays, 8€ on weekends/Kalamaki is free. In both places you can rent sunbeds, the cheapest is 2€ on Bolivar, waiters work, and you can order a cocktail with a sunbed. The beach bar is great, the food is delicious, the cocktails are strong. The atmosphere is good, music plays all day long on the entire beach.
