The Tăușoare-Zalion Reserve is a cave system located in the deeply forested areas of the Rodna Mountains, Bistrița-Năsăud County, in Romania.

The Tăușoare Cave was discovered in 1955 by a teacher, Leon Bârte.

Located at an altitude of 950 metres (3,120 feet), it has a length of 20 km (12 mi) and a depth of 413.5 m (1,357 ft),[1][2] making it the deepest and the third longest cave in Romania.

[2] The protected underground area covers 72.1 hectares (178 acres).

A few bones were transformed by the Palaeolithic man, who inhabited the cave, in tools.
