The Ochiul Beiului lake maintains a constant temperature of approximately 4-6 degrees Celsius year-round, preventing it from freezing.
The Nera River gorge is the longest in Romania, forming a natural barrier that has historically limited human development in the area.
The park contains endemic plant species that have survived in the sheltered microclimates of the deep, narrow gorges.
A significant portion of the park is covered by virgin beech forests, protected as UNESCO World Heritage sites.
The Bigăr Waterfall historically originated from an underground spring that flows into the Nera River after cascading over a porous limestone rock.
The Comarnic Cave system, located within the park, contains one of the most significant and diverse cave formations in the country.
Cheile Nerei-Beușnița National Park is a protected area in the Anina Mountains of southwestern Romania, characterized by the deep Nera River canyon and karst landscape. The park spans approximately 36,758 hectares and contains high concentrations of waterfalls, cave systems, and travertine formations. The Bigăr Waterfall, once internationally recognized for its unique moss-covered limestone cliff, experienced a partial natural collapse in 2021, though the site remains a major focal point for visitors. The Ochiul Beiului lake is noted for its vivid turquoise, frost-free waters that stay liquid even in winter due to continuous spring feeding. Hiking trails traverse steep cliffs, suspension bridges, and forested slopes rich in biodiversity, including brown bears and lynx. The park serves as a core part of the Nera River gorge, which is the longest in Romania, stretching over 20 kilometers. Extensive karst features include the Comarnic and Popovăț caves, which are significant for speleological research. The terrain is rugged, requiring visitors to navigate limestone rock formations and river crossings.
