Cala Luna
Highlight • Beach
The beauty of this bay is beyond compare. Here you can find shelter in the shade of one of the numerous caves or immerse yourself in the crystal clear waters, a true treasure of Sardinia. At the end of the bay, an oasis invites you to stop for a snack in the kiosk or for a picnic. Also watch out for bold goats grazing on the steep slopes!
If the walk back seems too challenging, you can always take a boat back to Cala Gonone or Cala Fuili.

The cave is not very large and the path to reach its entrance is a bit steep. Alternatively, you can take a small detour that goes around the cave.

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).

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!

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/

On the approximately 3.6 km long and 400 meter deep descent you will see many cave entrances, mostly on the right side. These are relatively small grottos.

Rocky and gravelly descent and ascent through the gorge over more than 500 meters in altitude. Sturdy, suitable footwear is essential. To walk through the gorge, an entrance fee of €6 per person must be paid at the beginning of the path (or probably also possible via the official Heart of Sardinia app), the number of visitors is limited to 250 per day. The hike can be started until 2 p.m., and you must set off at the bottom of the gorge at 4 p.m. (at least that was the case in October 2024, the times may vary in summer because it is light longer then). Take enough water and snacks with you, there is no opportunity to buy anything down at the bay. Despite the conditions, which require a bit of planning, the hike and the visit to the bay are definitely worth it. There are great views to enjoy and the bay itself is beautiful.
