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

6 euros entrance fee, which is really worth it. Opening times: Only with a guided tour, approx. 45 minutes - at the following times: 10:00 a.m., 11:00 a.m., 3:00 p.m., 4:00 p.m. and 5:00 p.m https://www.escursionisadali.it/ There are 5 rooms to visit. In contrast to the well-known grottos, the lighting is more temporary and the paths are more adventurous. The following legend surrounds the grotto: The cave is called “Is Janas”, which is a Sardinian name for “fairies”. According to a legend, three fairies lived in this cave. The fairies loved food and enjoyed cooking. This is also how you cook during Lent. A priest surprised the fairies while they were eating and was hanged by them (broken stalagtite in the first room). As punishment, God turned the fairies into three stalgmites (room 2). In the fourth room the skeleton of a "Prolagus Sardus" was discovered as well as ceramic shards from the Neolithic period (3000 BC) which can be viewed in the Museum of Caglari. Geological and historical information: The cave dates back 5 million years and was discovered in the 19th century. The cave is approx. 240 meters long and has a constant temperature of 12° and a humidity of 99 - 100%. The colors of the cave are: red (iron oxide and clay), gray (manganese) and black (guano - bat excrement).

Imagine standing on the highest point in Sardinia, Punta La Marmora, and your gaze sweeps over the entire island. On a clear day you can even see the silhouettes of Corsica on the horizon. You can put this experience into practice by hiking to the summit of this 1,834 meter high elevation. Ideally, start your tour in the parking area at Rifugio Sa Crista or Rifugio S’Arena near Desulo. The route is not short at 15.5 kilometers, but it rewards you with an incredible variety of landscapes. Within a walking time of three and a half to four and a half hours, you will cross picturesque forests, pass flowering meadows and hike across impressive boulder and craggy terrain. Among other things, it goes over the summits of Bruncu Spina and Punta Paulinu. As you climb from Bruncu Spina towards Punta La Marmora, a huge summit cross might lead you astray. But don't be fooled, because the true summit is only reached when you reach the small rock pyramid that marks the top of La Marmora. The peak itself was named after the general and scientist Alberto Ferrero della Marmora, who described Sardinia in detail in his works. His love for the island will become clear to you at the summit when you enjoy the breathtaking view. You should be well prepared for this hike. This means: Sturdy hiking boots, enough water and sun protection should be in your luggage. If you need refreshment in between, you can stop off in the towns of Desulo or Fonni. The months from June to September are ideal for the tour. But Punta La Marmora is actually a year-round hiking destination for everyone who is looking for something special. Ready for this adventure? Then lace up your hiking boots and experience Sardinia at its best!

Climbing to Punta La Marmora from Bruncu Spina you first reach the pre-summit, which is misleading with its enormous summit cross. To reach the highest peak in Sardinia, you need to continue further south until you reach a small rock pyramid. This marks La Marmora's peak share of 1,833.

Punta La Marmora, which rises 1,834 meters above sea level, is the highest peak in Sardinia. It is located in the Gennargentu massif. A cross crowns the top of this magnificent place. Running up here isn't difficult, except for some occasionally steep sections. It's not very technical; you just have to be fit. The breathtaking views make it truly extraordinary. You can see up to the lake of the upper Flumendosa, Perda Liana and Arbatax, if the fog allows it, and on the other side you can range up to Oristano. It's incredible.
