Astir Beach in Vouliagmeni has cabanas, umbrellas, beach-chairs, showers, a cafe-bar and an ancient Temple to Apollo. It is the most expensive of the beaches in Attika, 15 euros on weekdays and 25 euros on weekends, per person. Children up to 12 years old pay 8 euros. But it has everything a Greek beachlover needs to get through the day including umbrellas, sunbeds, showers, water-sports, restaurant, shops, beauty salon, newspaper stand, wireless internet and am I forgetting something? Oh heah. The sea. It is open from 8am to 9pm. You can take the metro to Elliniko and from there the 122 bus. A taxi will cost you about 20 euros or more from downtown but if you catch one at the Elliniko metro station it should be between 5 and 10 euros.
