Carved over millennia by the relentless force of the Flumineddu River, the Gorropu Canyon is a geological marvel often hailed as the “Grand Canyon of Europe”. Located within the wild limestone massifs of the Supramonte, its towering vertical walls rise up to 500 meters high, while the canyon floor is a labyrinth of giant white boulders. This wild, untamed environment is home to rare endemic species, such as the endangered Aquila chrysaetos (golden eagle) and ancient yew trees, making it a dream destination for experienced hikers and nature enthusiasts.
