The Kalamaris waterfall (Gialova waterfall, Καταρράκτης Καλαμάρης) is a nice 10 meter high waterfall north of Gialova
From Gialova drive north and soon take the exit right to Shinolaka. After 900 meter there is a (greek) blue traffic sign for the Kalamaris waterfall (Καταρράκτη Καλαμάρη) pointing to the right. Follow the dust road until it ends at an olive orchard (gps 36.957323, 21.727766). You can park your car here.
From the parking it is a 10-15 minute walk east until you reach the Kalamaris waterfall.
When there is enough water in the Kalamaris waterfall (Gialova waterfall) it is gorgeous and one of the most beautiful waterfalls in Greece. In summertime the stream can be very small but still the scenery is gorgeous and very picturesque.
