Finiki is a picturesque fishing village on the western side of Karpathos. If you're not staying here it is a beautiful village to visit for (half) a day. There is a small beach with a few sunbeds and parasols. The water is shallow and calm so it's also a great beach with kids! Multiple taverns are in the village for you to enjoy a delicious Greek meal. We'd recommend Mama Cuisine or Marina's (go for the Dolmades Kasos style!) for food and check out Poseidon or Malibu Beach café for cocktails.
The views of Arkasa village from the village are simply stunning and this is also a great area to watch the sunset!
