Skiathos island

Koukounaries
This is most famous beach of Skiathos and one of the most widely - known beaches in Europe. It is known as "Chrisi Ammos - Golden Sand" since the sand there is extremely fine and shines under the summer sun. This beach offers the visitors its deep-blue, crystal-clear waters and a unique chance for a rest since the forest of Koukounaries reaches down to the sea.
Banana 
This bay was originally called Krassa, but later it was named Banana after the nudist beach which used to be there. The pine trees here complete the beautiful landscape in a unique way and the sea shines brilliantly under the blazing sun.
Agia Eleni
The bay of Agia Eleni is named after the little country church found there and is dedicated to Saint Helen, opening its arms to the setting of the sun and the west. The sun shines until very late so if  you swim there, you will enjoy even its last rays. The crystal - clear bluish waters are inviting and the pine-trees reaching the sea will offer you their refeshing shade under their dense leafage.
