A tour around the northern part of the island of Náxos goes past unforgettable villages, churches, ruins and beaches, incuding: the tower of Belónia, a fine example of the fortified houses built by the Venetians; the magnificent Potamiá Valley; the Byzantine church and tower house in Halkí; the narrow streets and crafts in Apíranthos; the village of Apólonas overlooking a little harbour and a beach nestled in an inlet; and the Monastery of St John Chrysostom painted a dazzling white. Extensive views of the sea.
