Nera Gorges (Cheile Nerei): The Turquoise Wilds of the Anina Mountains +video and views
Posted: Sat Feb 14, 2026 3:15 pm
Located in the southwestern part of Romania, within the Cheile Nerei-Beușnița National Park, this area is a breathtaking display of limestone karst formations, crystal-clear turquoise waters, and untouched wilderness. Spanning over 22 kilometers, it is the longest gorge in Romania, offering a landscape that feels almost tropical due to its unique microclimate.
The Phenomenon of the Turquoise Waters
The most striking feature of the region is the color of the water. High concentrations of calcium carbonate give the springs and lakes a vibrant, ethereal blue-green hue.
Exploring the Tunnels and Trails
The gorge is famous for the "La Tunele" section—a series of small tunnels carved directly into the rock walls during the Roman Empire or the Ottoman period (historians still debate the exact origin). Walking through these hand-carved passages with the rushing Nera River below is a highlight for any adventurer.

- Ochiul Beiului (The Eye of the Bey) (see more): A karst lake that never freezes, maintaining a constant temperature and a mesmerizing shade of turquoise.
- Beușnița Waterfalls (see more): A series of tufa limestone cascades covered in emerald moss, creating a fairytale-like curtain of falling water.
- Biodiversity: The park is a "hotspot" for biodiversity. Due to Mediterranean influences, you can find the horned viper (Vipera ammodytes) (see more), the fire salamander, and rare orchids. The dense forests of beech and hazel provide shelter for the Carpathian brown bear and the European lynx.
