Groapa Ruginoasă: A living wound in the heart of the Bihor Mountains

Groapa Ruginoasă, located in the Apuseni Mountains, Bihor County, is a unique nature reserve that will fascinate you with its wild and dramatic natural spectacle. This huge ravine, with a difference in level of 100 metres and a width of almost 1 km, seems like a living wound in the body of the mountain, a testimony to the merciless force of erosion.

A fascinating and unique landscape:

  • The steep walls, coloured in various shades of red and orange, provide a striking contrast to the raw green of the surrounding vegetation.
  • At the bottom of the ravine, the water streams gather in small rivulets that meander through the stones, carving a miniature canyon.
  • In spring and after the rain, the Rusty Pit turns into a stunning spectacle as the water colours the ground red, creating a vibrant picture.

An area rich in biodiversity:

  • Although it seems like a hostile place, the Rusty Hollow is home to a variety of plants and animals adapted to this unique environment.
  • Rare species of mosses and ferns grow on the steep walls, and various species of birds and small mammals can be seen in the more vegetated areas.
