The Kakia Thalassa beach, a breath away from Athens
Kakia Thalassa beach in Attica, which has nothing to do with its name, is a mythical place. It is no coincidence that it is one of the nicest and cleanest in the basin. Where does she owe her name? The name of the area has its roots in Greek mythology. In a battle between the ancient Athenians and the barbarians, the Athenians asked for the help of the gods. Then, according to legend, as the Greeks were few in numbers, Zeus and Hades ordered Poseidon to cause large waves in the region. Thus, the tempest “swallowed” the fleet of enemies, and the Athenians were saved from certain havoc. During the summer months, the kakia thalassa is full of life.
The kakia thalassa has blue waters, a sandy bottom, and a coast paved with fine pebbles. They are ideal for taking a leisurely ride by the sea all year round. As for the summer months, the beach is divided into two parts and serves all tastes. The southern part is organized, with sunbeds, umbrellas, showers, and changing rooms. On the contrary, the northern part is free.
