The Greek island of Koufonisia is located in the Cyclades group of islands and forms part of the municipality of Naxos and Lesser Cyclades. The island lies to the south east of the island of Naxos and to the west of the island of Amorgos. Koufonisia is actually made up of three different islands: Kato (Lower) and Pano (Upper) Koufonisi and Keros which is uninhabited and is a protected archaeological site. Artefacts found on Keros during the 20th century include a large number of Cycladic pieces of art. Also uninhabited is Kato Koufonisia which is next to Pano Koufonisia, Shoinousa and Keros. Pano Koufonisi is the smallest and most densely populated island of the Cycladic island group. The small church of Panagia which has been built on a jetty above ancient ruins is perhaps the most popular sight on the island. The island's port is mainly used by tourist boats and fishing vessels. Visitors to the island are greeted by a white windmill which is located on the east side of the port. The main town on the island is Chora which is on the south west coast of the island and has many houses of typical Cycladic architecture.
The Greek island of Sifnos is located in the western end of the Cyclades group of islands and is typical of the islands of the Cyclades with its traditional architecture, lovely calm beaches, pretty tavernas and hills. The island's south coast is where most of its popular beaches are located and many have soft sand, crystal clear water and good facilities. A popular attraction on the island is the lovely Monastery of Chrissopighi which is the island's protector. The most picturesque village on the island is Kastro, which is surrounded on three sides by views of the Aegean Sea, and is characterised by narrow streets, stone built houses and beautiful views of the sea. The village can trace its history back 4,000 years with evidence of its past visible in many places and includes part of its defensive wall which was built in around 800 BC.
The island's port is located in the town of Kamares. During the summer months there are daily services of both high speed and conventional ferries to the island. Ferries connect Sifnos with Piraeus and to the other Cycladic islands such as Serifos, Folegandros, Kythnos, Milos, Ios, Santorini and Crete.
