Carry any certification or documentation your dog needs, since you could be asked to show it at boarding or partway through the crossing.

The Greek island of Sifnos is one of the Cyclades islands, and lies between the island of Serifos and the island of Milos. It is located to the west of Delos and Paros and around 130 km from Port of Piraeus on the Greek mainland. The island's capital is Apollonia, sometimes called Hora, and was built over three hills in the centre of the island in the shape of an amphitheatre. The town is characterised by its whitewashed houses in the typical Cycladic architectural style. The island's Folklore Museum is based in Apollonia, in Hiroon Square - which means Square of Heroes. One of the most popular visitor attractions on the island is the medieval castle located around 3.5 km from Apollonia. It was built on top of the island's ancient capital and still has the original characteristics of a Venetian fortification. It was established by the Da Corogna Dynasty in around 1635.
The town of Kamares is home to the island's port and during the summer there are ferry services operating to Piraeus, to other Cycladic islands like Serifos, Folegandros, Kythnos, Ios, Santorini and also to Crete.
The Greek island of Koufonisia is located to the east of the island of Naxos and to the west of the island of Amorgos, and is made up of two islets named Pano Koufonisi and Kato Koufonisi. The two islets are separated by a strait which is around 200 meters wide and the island's name is derived from the Greek for "Hollow Island" which is a reference to the large caves which led pirates to believe that the island was hollow when viewed from the sea. Located close to Koufonisia is the deserted island of Keros which has been declared an archaeological site that is under protection because of the many Cycladic artefacts that have been found on the island.
Pano Koufonisi is the only inhabited of the two islets and is a popular destination for visitors who want to relax on the island's golden sandy beaches or to swim in the island's war, crystal clear waters.
