Lake Sartai is located in Rokiškis and Zarasai municipalities, northeastern Lithuania. The lake's 79 km shoreline is the longest in Lithuania. There are six islands in the lake. River Šventoji flows through it.
The lake is famous for annual horse race that were organised on the frozen lake near Dusetos. Nowadays this tradition is abandoned because of safety requirements. The race is organised at a hippodrome on the shore of the Sartai Lake.
