Mount Vermio the natural boundary between the plain of Imathia and Thessaloniki to the East, and the highlands of Kozani to the West, allows a restricted amount of mandatory passages upon which the most significant towns of the area can be found: Veroia, the capital of the Prefecture of Imathia to the South, the city of Naoussa in the centre, and Edessa, the capital of the Prefecture of Pella, to the North. Many villages are dispersed between those cities, assuring the continuity of human presence.
The northern and eastern slopes of Mount Vermio are covered with coniferous forests (mainly with beech trees), while the western slopes are almost barren. Aliakmonas river defines the southeastern boundary of the mountain, while the rivers Tripotamos (southern Vermio – Veroia) and Arapitsa (central Vermio – Naoussa) contribute significantly to the formation of rich vegetation.
The springs that gush through the tufa rocks (travertine) form recreation constitute points of reference and of gathering for the residents. Such are the Three Wells, the Five Wells, Koutsoufliani, Michali Fountain, Jovana, Grammeni, Seta, the Isvoria. Famous springs are also those of Kara Bournar forming the river Mega Rema (Great Stream), which contributes substantially to the development of the Rhodochori – Giannakochori and Marinaregion.
The highest absolute altitude of the area is 2052 m (top Tsanaktsi in Naoussa). Other important peaks are the Black Stone (2027 m.), the Holy Spirit (2014 m.), Arsoumpasi (1874 m.), Ntourlia (1770 m.).
Waters coming form large and small waterfalls which were used as a driving force for industry from the 19th century. The greatest river, especially for Naoussa, is Arapitsa, whose springs are situated at Aghios Nicholaos Park, a fabulously beautiful area near the city. Flowing towards the lower plains, it crosses the city, whilst lower of higher waterfalls are formed through-out the river’s itinerary to the plain.
