The Crystal Cave in the Farcu Mine was discovered in 1987, following the advancement of the working front of the Farcu Mining Gallery. The cave is 251 m long and 16 m high. At the time of its discovery, the cave was considered a true gem, due to the richness of the speleothems, the diversity and shapes of the crystals existing here. Unfortunately, after the discovery, the cavity was damaged countless times by the breaking and destruction of the crystals. Recent explorations currently bring the Crystal Cave in the Farcu Mine back into the gallery of the most beautiful caves in Romania. The visitable route will cross 200 m of mining galleries, where you will also have the opportunity to visit a mining museum and 100 m of cave galleries with walls shaped by water and adorned with unique formations and crystals. The tourist route ends at a balcony from where you can admire the crystal reserve with the famous Farcu discs and the "crystal dragonflies".
