The sea bottom in Koufonisi is majestic as well as friendly and while approaching Keros it becomes unsurpassed, ideal for diving enthusiasts. The south-eastern coasts of the island have the most beaches, starting with Finikas, Fanos and Platia Pounta or Italida which is the busiest. Afterwards you will meet the “swimming-pools”, small coves between rocks where you can swim comfortably and Pori, the most beautiful beach of the island. The rocky caves on the northern coasts of Koufonisi and in Kato Koufonisi are ideal fishing grounds and will enchant the amateur fisherman.

There are fishing boats that execute regular itineraries from Hora to the most distant beaches of the island, as well as for the near islets of Prasoura, Glaronisi, Voulgari, Tsouloufi, Lazarus and Megali Plaka with its amazing aquamarine beaches that have been declared regions of particular natural beauty.
