Beautiful hike through enchanted forest to the Domus de Janas. These are pre-Nuragic burial caves of the Ozieri culture (ca. 4000-3200 BC).

A breathtaking view of the mountains opposite. Beautiful path, which cannot be seen on the maps. The rear grotto (Janas) itself has only a few small stalactites.
