Lake Prespa is actually two lakes: Megali Prespa and Mikri Prespa, Great and Small: that straddle the borders of Greece, Albania, and North Macedonia. Megali Prespa is the larger, shared by all three countries. Mikri Prespa is smaller and almost entirely within Greek territory, separated from its neighbour by a narrow strip of land. The lakes are among the oldest in Europe. They sit at 853 metres elevation in a valley ringed by mountains. The water is clear, cold, and home to more than 260 species of bird.
A Transboundary Wetland of International Importance
Lake Prespa is actually two lakes, known as Megali Prespa and Mikri Prespa, straddling the borders of Greece, Albania, and North Macedonia. Together they form one of the most important transboundary wetland ecosystems in the Balkans. The larger of the two, Megali Prespa, covers roughly 259 square kilometres and reaches a depth of 54 metres. The smaller Mikri Prespa, almost entirely within Greek territory, is shallower and more significant for its bird populations. The lakes are connected by a narrow channel, and their waters are renowned for their exceptional clarity, with visibility reaching up to 15 metres in certain conditions. The entire region was designated a Ramsar Wetland of International Importance in 1975, and Mikri Prespa is also a Special Protection Area under the European Union’s Birds Directive.
Birdwatching Paradise and Island Monasteries
The Prespa lakes are home to the largest breeding colony of Dalmatian pelicans in the world, with over 1,400 pairs nesting on the small islands and reed beds of Mikri Prespa. Other notable species include pygmy cormorants, spoonbills, glossy ibises, and more than 260 other bird species recorded in the area. The best birdwatching months are April through June, when the breeding season is at its peak. Beyond the wildlife, the lakes are dotted with several small islands, the most famous of which is Agios Achillios in Mikri Prespa. This island is accessible by a short wooden footbridge from the shore and features the ruins of a 10th-century Byzantine basilica dedicated to Saint Achillios, along with a small traditional settlement and a handful of tavernas serving local fish dishes.
Practical Information and Local Traditions
The Greek side of Lake Prespa is accessed via the town of Florina or the village of Prespes, which serves as the main gateway for visitors. Accommodation options include guesthouses in the villages surrounding the lake, with several offering homemade local products such as bean soup, trout, and the region’s famous red wine. Boat trips around the lake are available from the small harbour near Agios Germanos, and guided birdwatching tours can be arranged through the Prespa National Park information centre. The best time for a visit is late spring or early autumn, when the weather is mild and the bird activity is at its highest. Winter can be cold and foggy, while summer brings warmer temperatures and the chance to swim in the lake’s clean waters. Entrance to the park is free, though there is a small fee for the boat tour to Agios Achillios island.
The Birds of Prespa
Lake Prespa is one of the most important bird habitats in Europe. The Prespa National Forest, established in 1974, protects the area. The most famous resident is the Dalmatian pelican, the largest freshwater bird in the world, with a wingspan of up to 3.5 metres. Prespa hosts the largest breeding colony of Dalmatian pelicans in the world, with roughly 1,400 pairs. The pygmy cormorant, the glossy ibis, the spoonbill, and the white-tailed eagle also nest here. The best birdwatching is from the observation hides at the Mikri Prespa wetland, accessible from the village of Psarades. Early morning is the active time. The hides are free. Bring binoculars.
The Island Monastery of Agios Achilleios
On the tiny island of Agios Achilleios in Mikri Prespa, connected to the shore by a 650-metre floating bridge, stand the ruins of a 10th-century Byzantine basilica. The church was built by the Bulgarian Emperor Samuel in 990 AD, who made the island the seat of his patriarchate. The basilica is in ruins: the roof is gone, the walls are waist-high in places: but the floor plan is intact, and the remains of the marble iconostasis and the fresco fragments are still visible. The island is accessible from April to October. The bridge opens in late spring. In winter the island is accessible by boat from Psarades. The view from the island across the lake, with the Albanian mountains in the background, is the view the monks had for 500 years.
Getting to Lake Prespa
The lake is remote. The nearest town of any size is Florina, 50 km to the east. From Florina the road follows the valley west, past the village of Pisoderi at 1,300 metres, then descends to the lake. The drive takes about an hour. The village of Psarades, on the Greek shore of Megali Prespa, is the main base for visitors. It has a handful of guesthouses, a few tavernas, and a population of about 100. Accommodation is basic. A double room costs €40-60 per night as of 2026. The best months are May and June, when the birds are nesting and the wildflowers cover the shore. September and October are quieter. The winter is harsh. The lake freezes in January and February.
Would you cross the floating bridge to a 1,000-year-old monastery on a lake shared by three countries, or is that a place that belongs to the birds?
