Livadi is the largest settlement of the island and the only port of Serifos. It is located in the South-Eastern part of the island, in a bay protected from the meltemias. It has a good berth for ships in all weathers and a tourist shelter for boats.

Serifos is connected to Athens with regular ferry services from the port of Piraeus. There are also frequent ferry routes to Sifnos, Milos, Kythnos, Kimolos and other islands of the Cyclades.

Livadi is home to most of the island's accommodations and is generally the tourist center. There is a Bank, Post Office, Gas Station, Pharmacy, Port and Police Station and Information Office for visitors to the island, tourist offices and many shops.
