The entrance to Gruet Cave, also known as Gruiețului Cave, is strikingly grand with a portal spanning around 15 meters in width and 8 meters in height. Located on the left side of the Șteaza Valley, the cave's main gallery stretches for 50 meters and features limestone or calcium carbonate concretions. One should be cautious about the water level during rainy weather, which can significantly rise as indicated by a black streak on the cave's wall. Upon closer inspection, the stalactites at the entrance are all tilted inward, an effect of the wind over time. Also noteworthy is the bat guano found within the cave. This rich fertilizer was so valued that it used to be exported by train by the Hungarians when this region was under Hungarian control.
In the Bihor region, specifically in the community of Rosia, lies a captivating natural wonder: Gruet Cave, also known as Gruiețului or Grust Cave. A river flows through the cave, a fascinating byproduct of the melting glacier above the Apuseni Mountains. The cave opens with an impressive 15-meter-wide and 8-meter-high portal leading to a 50-meter-long main gallery, a sanctuary of limestone formations. What makes it even more remarkable is the presence of deep fissures filled with water that can be deceptively transparent and deep, requiring extreme caution.
The environment inside is not as cold as one might expect due to rainwater mixing with the glacier runoff, making it more hospitable for its primary inhabitants: bats. These creatures can be found throughout the cave, not just near the entrance. Visitors should also take note of the water levels during rainy weather, as they can rise dramatically, a detail indicated by a black stripe on the cave wall.
After your journey, washing off your gear in running water and enjoying a good swig of whiskey are essential. The cave stands as a vivid reminder of the rich geological and biological diversity the region has to offer, adding an enthralling chapter to any adventure.
