The Platanias River (Keritis) is located in northern Crete, within the Chania regional unit, west of the city of Chania, and flows into the Cretan Sea near the area of Platanias.

It is one of the most important rivers in western Crete and is closely connected to the natural and agricultural landscape of the region.

The river originates from the slopes of the White Mountains (Lefka Ori) and crosses a wide and fertile valley before reaching the sea. Its flow is mainly seasonal, with increased water levels during the winter months, while in summer it is significantly reduced, following the typical pattern of most rivers in Crete.

Along its course, the Platanias River (Keritis) forms an important agricultural zone, where olive groves and cultivated land dominate. The presence of water enhances vegetation and supports small ecosystems with reeds and riparian plants.

At its mouth, near Platanias, the river creates a small wetland area that adds diversity to the coastal landscape and contributes to the biodiversity of the region. This transition zone between inland and sea gives the area a distinct natural character.

The Platanias River (Keritis) is a representative example of the rivers of northern Crete, playing an important role in shaping the landscape and supporting the agricultural life of the area.
