The cave Forat Micó is known for long time ago in the Mountain of Salt of Cardona. It’s 640 m length and some of its walls are decorated with delicate crystalls of halita. Caves in salt rock are not just so beautiful, they’re also really rare in the world because the presence on the surface of water soluble salt rock is not common.
The mining in the second half of century XX disturbed the hydrologic balance in Cardona. As a result, water opened new channels, a new endo-karst process broke out into the salt environment below the level of Forat Micó. The new endo-karst combines old, reshaped mine galleries with new ones recently opened by water.
