Really nearby Gialova are the kalamaris waterfalls. It is a small hike, about 15 minutes to get to the waterfalls. From there, is a new path to hike to the Stenosia Waterfall. It is really worth the hike!
Many valleys cut through the hills covered by olive groves and natural vegetation around Gialova, and some of them hide wonderful waterfalls, such as the Kalamari waterfall by Schinolaka (the closest to Gialova), Polilimnio by Kazarma and the waterfall of Valta near Gargalianoi.
All these waterfalls can be easily visited on foot along footpaths that have been purposely created.
