Lake Ohrid

Lake Ohrid is old in a way few lakes are. Most bodies of water fill with sediment and disappear within tens of thousands of years; Ohrid sits in a tectonic rift in the mountains between North Macedonia and Albania that began opening some millions of years ago, and its oldest sediments may date back three to five million years. It survives because it is deep — up to 288 m, the deepest lake in the Balkans — because the ground beneath it is still sinking, and because much of its water arrives not by muddy rivers but through underground karst channels from Lake Prespa, 10 km away and some 150 m higher, emerging as springs along the eastern shore and beneath the surface.

That filtered water gives Ohrid its astonishing clarity: on a calm day you can see down some twenty metres. It also sustains one of the most remarkable freshwater ecosystems in the world. Like Baikal and Tanganyika, Ohrid has evolved its own species at every level of the food chain, from algae and sponges to snails, crustaceans and two endemic trout; around 200 species live nowhere else, and almost four-fifths of its molluscs are unique to the lake. The Macedonian shore was inscribed as a UNESCO World Heritage Site in 1979, extended the following year to the cultural heritage of the town of Ohrid and, in 2019, to the Albanian side; the wider Ohrid–Prespa area is also a transboundary biosphere reserve.

The lake measures about 30 km by 15 km and is shared roughly two-thirds to one-third between the two countries. Its shores carry an equally deep human history. Near Lin on the Albanian side, archaeologists have excavated a pile-dwelling settlement more than 8,500 years old, the oldest of its kind in Europe; the Roman Via Egnatia once passed close by on its way from the Adriatic to Constantinople. Today the historic town of Ohrid, Struga near the lake's only outlet, the Black Drin, and Pogradec in Albania are the main lakeside towns, and religious monuments such as the monastery of St Naum and the Black Madonna south-west of Struga stand on its shores. The last large reedy wetland on the lake, Studenchishte Marsh near Ohrid, shelters relict plants and endemic species.

Getting there

The town of Ohrid lies on the north-eastern shore, about 12 km from the middle of the lake. Ohrid St. Paul the Apostle Airport (OHD) is about 16 km away. A minor road circles the lake, with border crossings between North Macedonia and Albania, and part of the Macedonian shore lies within Galičica National Park.
