"Asteras Glyfadas Beach Sometimes a day at the beach, soaking up the sun and gazing out over sparkling waters, soothes the soul. Athens' southern districts offer a string of sandy options right in the city. Especially good for children on this "Athenian Riviera" is Asteras Beach. The waterfront is sandy and clean, the water is shallow and generally calm, there are inflatable water toys for kids to play on, and a seaside pool for older kids to lounge around. And for parents there's a well-stocked beach bar. Asteras is worth the entrance fee, and it's even reachable via tram from the city center. Easy, relaxing, restorative—and the sunsets here are stunning."
