The best MTB trails in Foresta Demaniale Del Marganai

The Su Mannau Caves, near Fluminimaggiore, are a unique feature of their extensive cave system, among the oldest in the world. With its two branches, they are also of great archaeological and speleological interest. The right-hand section consists of an extensive karst complex of Cambrian origin and extends over several levels. Some are higher and already fossilized, others deeper and still active. The right-hand branch was formed by the Rapido River and consists of numerous and varied passages and halls, which are the most interesting sight in the cave. The first hall is of great historical importance, not least because of its connections to the nearby Punic-Roman temple of Antas. A must-see!

In a lush valley around Iglesias lies one of Sardinia's most important Roman monuments. Originally a nuragic sanctuary, it was also used during the Carthaginian and Punic-Hellenistic periods. Built from local limestone, the sanctuary is nestled in a picturesque valley in the Fluminimaggiore area.

The cave is accessible from both sides, but the official entrance, where the ticket office and information point are also located, is the south one, on the opposite side. It is also possible to enter from this side by ringing the intercom and waiting for an operator to come and open the door for you. Entrance to the cave is subject to a fee and is only possible during opening hours. More information is available on the website: https://www.grottasangiovanni.com/

The Linasia Mountain Garden reconstructs the natural environments typical of the Marganai area over approximately 9,000 square meters. Located next to renovated mining buildings, it is home to numerous local botanical species, some of which are very rare, such as the Monte Linas helichrysum and the Sulcis pinnacle. Guided tours are available during certain times of the year. For information, please contact the Forestry Authority at +39 0781 20060.

During the first half of the 20th century, the village of Malacalzetta was an active mining center, with over two hundred miners, homes, offices, an infirmary, and a small washery. The origins of the Malacalzetta mine, located at the foot of the Marganai massif, date back to the Middle Ages, but modern mining began in the 19th century, with lead and zinc production continuing until 1986. Today, the site is immersed in the silence of the forest and preserves clearly visible remains: the large rooms where the workers lived, the lime kilns, and the washery arches in the Baueddu area.

The Temple of Antas stands in the splendid Antas Valley, a natural amphitheater intertwined with over three thousand years of history. The Nuragic people practiced rituals and burials here since the Bronze Age, followed by the Carthaginians, who erected a sanctuary dedicated to the god Sid Addir Babay, and finally by the Romans, who in the 2nd century AD rebuilt the temple in honor of Sardus Pater Babai, the patron deity of the Sardinian people.

The Su Mannau Cave is one of the most spectacular karst caves in Sardinia. It extends for approximately 8 kilometers, although the accessible section is limited to a 500-meter path through walkways, rooms, ponds, and underground waterfalls. The first part of the visit leads to the archaeological hall, an ancient underground temple used as a water cult in the pre-Nuragic era, connected to the nearby Temple of Antas. Continuing, you enter a living environment, where stalactites, stalagmites, and alabaster flows are reflected in the clear water, home to the Stenasellus nuragicus, a tiny crustacean unique in the world. The cave is open for guided tours year-round: information and hours at https://www.sumannau.it/

The Su Zurfuru mine was discovered in 1889 and for decades was one of the most important mining centers in the area. Originally dedicated to lead and zinc mining, the mine converted to fluorite mining after the war, but finally ceased operations in 1993. Today, the site has been restored and made accessible to visitors thanks to the Su Zurfuru Mine association. The Mining Memory Museum is open daily by reservation only.
