The river Keritis is located near Chania and belongs to the rivers with the largest water supply in Crete. It gathers the waters of the massif Lefka Ori from the area of Zourva and Meskla. After a course of more than 25 km it ends at the beach of Platanias. During its flow it merges with many streams and tributaries.
The ancient name of the river is Iardanos. It flows through the fertile plane of Alikianos, where there is also the historic arched bridge of Keritis where 108 locals were executed by the Germans in 1941. Then it ends up in Platanias, which is named after the many platan trees thriving in its bed.
