Kos is the main harbor on the island. It is a large and safe harbor although it is subject to N-NE winds which can cause considerable swell within the large harbor. As an alternative a yacht can go the near by Kos Marina.
In the last few years the harbor has been changed due to new extensions. Now yachts can moor on either the E side of the harbor under the castle or on the NE side, outside the harbor, when the weather is settled.
The S side where yachts used to anchor is now reserved for the many day-trip caïques. Go wherever there is room. Expect the harbor to be crowded during the summer months. Anchor in about 5 m depths and go stern-to to the quay. Excellent holding on mud.
The quay under the castle now has water and electricity outlets, although these are only available during peak season (July - September) when the quay is manned and a charge is made.
Outside those months mooring is free but there are no facilities. Many supplies can be obtained in the town, but due to the extremely large number of tourists the town has lost its soul.
Marina Kos is located on the outskirts of Kos town; about 15 min walk from the town center, next to Kos old harbour. Marina Kos is easily accessible, only 26Km away, through Hippocrates International Airport (IATA: KGS) by charter flights from the major European cities.
Lake Psalidi is near Kos town and is a great destination for bird-watching, providing birds such as rare ducks and flamingoes. Some of the species, which could be found there, especially in the autumn, include Reddy Shelduck, Slender-billed Curlew, Long-legged Buzzard and Lesser Kestrel.
The Archaeological museum of Kos is located at Eleftherias square, in a neoclassical building, designed in 1935. Excavations brought to light findings by the beginning of the century, mainly from the archaeological site of the Market and also from monuments, such as, the Altar of Dionisos, the Odeon and the Roman Residence.
