Leros Island still holds the "purity" of it as you can say that sinks from tourism, even in high season the Assumption. At Leros you will see the traditional Greek island style whitewashed houses with blue doors and windows, but you see, and others, built in Italian style (Lakki). All harmoniously combined, the quiet streets of the island. The many beaches and blue (Xirokambos, Vromolithos, Two Liskaria). In most tourist, Alinda, you can try your luck in some surfing, but if you're at the lounger, rest under the shade of pine trees that stretch along the beach. Idyllic summer moment. As for the evening? Both Panteli with taverns will lick your fingers from fresh fish, and the coastal area of Agia Marina, you can get a taste of Leros entering the narrow streets. The latter (Agia Marina) is the tourist heart of the island. Somewhere in the evening, sit for a while somewhere where you will see the discreetly illuminated castle and Mary Mills of Leros. If you have the courage, however, after so many bathrooms and such food, climb the 500 steps and see the panoramic view of the island (with until you see clear skies and Patmos) in a breathtaking landscape. Worthwhile.
Vonus: The church of St. Isidore was built on an ancient temple on a small island passable by land. Even if you're not a fan of the churches go!
