They are called this because, when viewed from a distance, they resemble the heel of a shoe. These limestone-dolomite mountains are scattered throughout the Ogliastra region: the most famous is Perda Liana, located in the municipality of Gairo.
Here are a few more: the heel of Monte Tisiddu, the Arba heel (Ussassai), Monte Lumburau, Monte Arquerì, the Anuill’e Ferru heel and Punta Corongiu in Jerzu.
If you enjoy long walks and trekking, there are several trails where you can discover these important natural monuments.
