Green Lakes
Six deep lakes of glacial origin in forest on the north-eastern edge of Vilnius, bright green from the carbonates in the groundwater that feeds them.
Updated 8 November 2026
The Green Lakes, Žalieji ežerai, are six lakes in forest on the north-eastern edge of Vilnius, inside Verkiai Regional Park and protected as a landscape reserve. They lie in very deep, steep-sided channels cut by the meltwater of a retreating glacier about 18,000 years ago, and their bright green colour comes from the high carbonate content of the groundwater that feeds them. Around Balsys, the largest at 55 ha (136 acres), steep wooded slopes rise up to 40 m (131 ft) above the water and drop almost as far below it; the others are Gulbinas, 36.8 ha (91 acres), Little Gulbinas, 10.4 ha (26 acres), Raistelis, 1 ha (2.5 acres), Akis and Baraukos Akis. Cycle paths run around the lakes and town beaches line the shore, so people come here at every time of year, and many plants grow on the banks, some of them rare.
