The port city of Piraeus in Greece lies on the Saronic Gulf in the Attica region of the country and forms part of the Athens urban area, with the centre of Athens located some 12 km from the port. The centre of Piraeus is generally congested with traffic and tends not to be place where tourists would go. The area has many of the facilities you would expect of a non-tourist town: banks, public buildings, pedestrian areas, shopping streets and the like. The area around Zea Marina and Mikrolimano Harbour are perhaps the most attractive part of Piraeus and have a good selection of restaurants, cafes and bars.
Piraeus is Greece's main port and the largest in Europe and the third largest in the world. Unsurprisingly, it is the hub of Greece's maritime industries and the base for its merchant navy. Having recently undergone a refurbishment, facilities at the port have improved and include ATM's, bureau de change, restaurants, cafes, bars and a number of travel agencies selling ferry tickets. destinations served by the port include the island of Crete, the Cyclades Islands, the Dodecanese Islands, the eastern parts of Greece and parts of the northern and eastern Aegean Sea.
Kythnos is a Greek island that is located very close to Attica and is part of the Cyclades group of islands. The island, sometimes called Thermia because of the thermal springs on the island, is one of the lesser visited islands of the Cyclades but is popular with visitors because of its thermal springs. There is a modern spa located in Loutra, with two hot springs in the area. The spring of Ayio Anargyroi and the spring of Caucasus, where the temperature of the water reaches 52C, are famous for their therapeutic effects and have been since ancient times.
The island's harbour is located at Merihas and the island's capital is called Hora and are both located in the north of the island. In the south, only the areas by the bay of Ayios Dimitrios and Panayia Canála are inhabited. This is where a famous monastery is located within a pine forest.
Ferry services from Kythnos depart to the Port of Piraeus or to the port of Lavrio. The crossing to Piraeus takes approximately 3 hours by conventional ferry and approximately one hour by high speed ferry. The crossing time to Lavrio takes about 2 hours. Kythnos is also connected by sea with the islands of Serifos, Sifnos, Milos, Santorini, Sikinos, Folegandros and Kea.
