The Krios River flows from the area of Chionistra in the Troodos Mountains, in a direction towards the south and crosses Pano Platres and Kato Platres from the east.
It creates a green valley with unique fauna and flora as well as waterfalls. Along its path it creates the Caledonia Waterfalls as well as the Millomeri Waterfalls which are the most famous ones on the island. Many tourists and locals visit the waterfalls and walk along the various nature trails in the area. The water flow is constant, with increases and decreases according to the weather conditions.
The river is a source of life for the community of Platers as well as other surrounding communities. The Krios River pours into the delta that is formed at the Kouris River along with other smaller river, creating the famous Kouris River and finally pouring into the Kouris Dam.
