The Kiliaris River is located in northern Crete, within the Chania regional unit, in the Apokoronas area.

It is one of the most important rivers on the island and flows into the sea at Kyani Akti Beach, near the village of Kalyves.

The river originates from the springs of Stylos, at the foothills of the White Mountains (Lefka Ori), and has a total length of approximately 5 kilometers. It is fed by strong freshwater springs and tributaries, which allow it to maintain a continuous flow throughout the year, a rare characteristic for rivers in Crete.

Along its course, the Kiliaris River crosses a particularly fertile valley, rich in olive groves, cultivated land, and dense vegetation. Its banks are lined with plane trees, reeds, and water-loving plants, creating a lush natural environment. In antiquity, the river was known as “Pyknos,” a name associated with its dense vegetation.

The river also features a notable network of tributaries, and in the past, several watermills operated along its banks, highlighting its importance for local agriculture and traditional economic activities.

At its mouth, near Kalyves, the river forms a distinctive landscape where freshwater meets the sea. This area functions as a small wetland, supporting biodiversity and adding ecological value to the coastal zone.

The Kiliaris River stands out as one of the few rivers in Crete with a permanent flow, playing a significant role in shaping the natural landscape and sustaining the environment of the Apokoronas region.
