The Edessa waterfalls - Greece’s largest waterfalls - are quite exceptional. Centuries ago people made a bassin for their water supply, but in the 14th century the river changed it course ((perhaps after a geologic or weather phenomenon) creating first one waterfall but later on several other small waterfalls.

The most impressive waterfall - called Karanos - has a height of 70 meters. The smaller twinfall is called Lamda. It is possible to walk behind the big Karanos waterfall where one has a perfect view with a water curtain (PiP 4).
