Emerald-green and tree-fringed, this small reservoir just northeast of Zaros was created in 1987 to store the town’s natural spring water. It attracts scores of birds and is great for chilling in the shady park or munching away in the excellent taverna-cafe. A path accesses both Moni Agios Nikolaos (1km) and Rouvas Gorge (2.5km).
