Dusia Lake is one of Lithuania's largest lakes, located in the south of the country near Lazdijai. It is a popular kitesurfing spot among Lithuanian riders thanks to its large flat water surface.

The lake offers ideal flat water conditions for freestyle and learning. The depth is moderate with a sandy bottom in places. All wind directions work thanks to the elongated shape of the lake.

Dusia Lake is set in pleasant natural surroundings. Several access points exist around the lake. The season runs from May to October. The spot suits beginners and intermediates.
