A uniquely shaped, towering tower, a natural monument, symbol of Ogliastra, and a key morphological feature of central-eastern Sardinia. Perhaps once a gathering place for the Nuragic peoples, it later became, in popular legend, the entrance to the underworld. It protrudes from the earth like a giant finger reaching toward the sky and, especially in this wild area, is a landmark visible from afar for hikers. Perda 'e Liana is an extraordinary rock formation declared a natural monument in 1993. The peculiar "mountain," known in Sardinian as Taccu or Tonneri, rises in the Gairo Sant'Elena area: it is the greatest witness to the erosive effects of weathering that have been affecting the vast limestone cover of Ogliastra on the border with Barbagia di Seulo for several million years. Erosion gradually isolated the "tower," forming its base. It is the highest (1293 m) of the numerous Ogliastra limestone mountains, the northern foothills of the Tonneri plateau, about two kilometers away, to which it is connected by the s'Arcu 'e su Pirastu Trottu pass. Perhaps in ancient times, they formed a single mountain ridge. Source and further information: https://www.sardegnaturismo.it/de/entdecken/perda-e-liana

On Monte IDOLO, hikers will not come across a summit cross - as is often the case. The small sacred monument that instead rises above Sardinia is a statue of SAN MICHELE ARCANGELO. The heavenly messenger is equipped with powerful wings, which give him an imposing figure. However, one will look in vain for a sword or a lance, which are often given to him as an attribute.

The Rocce Rosse (Red Rocks) cove is located east of the port of Arbatax. It offers a backdrop of white rock and high red granite cliffs that give it a unique and extremely fascinating appearance. The environment could be a little better designed.

The rock is a highlight. The surroundings can't compete with it.

The “Red Rock” is an eye-catcher. The environment, not so much.

The cave is very worth seeing. We can also recommend the restaurant.

The Rocce Rosse bay opens to the east of the port of Arbatax, a tourist district of Tortolì, with a bottom of white rocks and high red granite rocks, which give it a unique and extremely fascinating appearance. Their reflection gives the water an iridescent color on emerald green.
