Prespasjøen

The Lake Prespa is located on the tripoint of North Macedonia, Albania, and Greece. It is a system of two lakes separated by an isthmus: the Great Prespa Lake, divided between the three countries, and the Little Prespa Lake, mostly within Greece. They are the highest tectonic lakes in the Balkans, standing at an elevation of 853 metres.

The area contains three national parks: Prespa in Albania, Galičica in North Macedonia and Prespa in Greece. The largest town in the region is Resen in North Macedonia. In 2014, the Ohrid-Prespa Transboundary Reserve between Albania and North Macedonia was added to UNESCO's World Network of Biosphere Reserves.
