The waterfall of Rehtra is located in the location Kaimenos, south of Panasos, southwest of the place where the ancient Assos is believed to have been built. The stream that flows through it is called Argyropotami, it is a tributary of the Litheos river and starts from the valley Lenika.
The waterfall is about 20 meters high and has water until early summer. Its rocks have impressive colors and shapes with many stalactites, while the backdrop is uniquely complemented by the water-loving plants that have grown on its cliff.
The locals also call it the waterfall of the Nymphs, as they believe that at the site there was a Nymphaeum (sanctuary) connected to the ancient city of Assos. The legend wants to be inhabited by Naiads in antiquity and Fairies in recent years.
Access is through a network of dirt roads starting from Apomarma or Panasos. Until recently it was impossible to reach due to dense vegetation of figs and raspberries, but a path leading to its base was cleared.
