Potami Waterfalls ( Samos ) are three kilometers from Karlovasi in the "river district". They have outstanding natural beauty and form two small lakes, ideal for the adventurous who want to swim in their icy waters. To admire the waterfalls up close, you will have to drive to the river and walk 1.5 km to reach the Church of the Transfiguration, the oldest church on the island, which dates from the 11th century. The Church is exactly the halfway point of this journey. From there you will continue going, climbing about 50 wooden stairs to get to the first waterfall.
