Delfini Syros: The beach of Delfini is located on the northern coast of Syros, on a very nice bay and can be easily reached. It is a clean beach with sand and pebbles, great for swimming and relaxing. It is sheltered and protected from winds.
As this beach is quiet enough, it is regularly chosen by nudists, who usually go to practice nudism on the rocks at the far end, which form a series of low shelves. There aren't many facilities on this beach, except for a tavern, so make sure you get supplies with you.
