The coastal settlement of Ai Dimitris is situated right after Kalamakia. The region has a small hydro land for emigrating birds. Previously it used to hold water for eight months and hosted rare species of birds. But now it only keeps it for two months. In Ai Dimitri you will see the biggest and for many the most beautiful beach in Alonissos. White pebbles and crystal clear waters create an exotic beach that every visitor should see. It is not accidental that it is considered one of the most crowded beaches in Alonissos.
