Koukounaries is the most famous beach of Skiathos, Greece.

Two kilometres long stretch of golden sand, azure water and green pines, the most famous beach of Skiathos island and reputed to be the best in the Aegean sea.

Koukounaries (Greek: Κουκουναριές, meaning "pine cones" after the trees surrounding the beach), is a site on the island Skiathos (part of the Sporades), 16 km southwest of Skiathos Town, Greece. Koukounaries was once known as Maratha (Μάραθα). Koukounaries is well known for Koukounaries Beach, also known as "Chrisi Ammos" (Greek: Χρυσή Άμμος, meaning "golden sand") since the sand there is extremely fine. Until 1964 when Skiathos was designated by the Greek National Tourism Organisation as a development zone for tourism, Skiathos town was the only settlement on the island. Following the GNTO's decision a coast road connecting Skiathos town to Koukounaries was built. At the same time the first large scale hotel on the island was built in Koukounaries. Currently, Koukounaries is a popular tourist destination during the summer. There is a large variety of hotels, hostels, camping sites, tavernas, restaurants, bars, "ouzeri", and cafes.
