Lake Bernhardsthal (also: "Bernhardsthaler Teich") is located in the very north east corner of Lower Austria near the border with the Czech Republic. The lake has a size of approximately 0.5 km² and is free for bathing, fishing or boating.

Its clear, jade water is especially beautiful in spring. The Lake can also be reached from Marchegg.
