Florina is the gateway to the Prespa Lakes and, until the modernisation of the road system, of the old town of Kastoria. It is located west of Edessa, northwest of Kozani, and northeast of Ioannina and Kastoria cities. Outside the Greek borders it is in proximity to Korçë in Albania and Bitola in the Republic of Macedonia. The nearest airports are situated to the east and the south (in Kozani). The mountains of Verno lie to the southwest and Varnous to the northwest. Winters bring heavy snow and long periods of temperature below freezing point. Furthermore, the town and the surrounding valley is usually covered in thick fog during the winter months that may last even for weeks under specific conditions. During the summer months it becomes a busy market town with an economy boosted by summer and, mostly, winter tourism due to the heavy snowfalls and the nearby ski resorts.
