Gleinkersee is situated in the Windischgarstner basin, 2 km (1.2 mi) southeast of the town center of Rossleithen.

Only at the northern shore around the outlet via the Seebach it contains a narrow muddy strip in front of a shallow meadow bank.

[2] During the ice ages, a glacier flowing from the cirques at the north slope of the Totes Gebirge formed the Gleinkersee's basin.

[3] Gleinkersee ist a popular day trip destination for hiking, due to the scenic views of Totes Gebirge and Nationalpark Kalkalpen.

Facilities at the north shore include Gasthof Seebauer, an inn, a camping site, two ropes courses and a rental for boats and paddle boards.
