ŠULNIO, GULBINO AND KERNAVĖ LAKES
There are three lakes in Rūdninkai. “Kernavė” lake (81 hectares) is surrounded by swamps and mostly black alder or low pine trees growing on the fens. “Šulnio” lake (just 1.5 hectares), is also placed by the marshlands and swamps. It is a typical dystrophic type bog lake, a great habitat for small blossom water lilies. Towards south east Rūdninkų, close to the wetlands surrounding the continental dunes, you will find “Gulbino” lake.
