From a hill 260 metres above sea level the village overlooks the banks of Lake Omodeo, in the Marghine mountains, with a landscape that has few equals, ideal for trekking, mountain biking and canoeing, as well as a natural park and refuge for rare birds. Bidonì is one of the island's smallest villages, with just 150 inhabitants, and falls into the historical region of Barigadu. The earliest documents that mention the village where today's centre stands date back to 1157. Walking through the narrow streets is like going back in time: cobbled streets, medieval monuments and ancient homes in red trachyte stone, including sa ‘Omo ‘e sa majarza (the witch's house), which tells all about witchcraft and the Inquisition in Sardinia. Today, the traditionally agricultural hamlet is part of the Borghi autentici d’Italia circuit and the Domos Rujas comunità ospitale (tourism hosting organisation), together with the other "borgo autentico" Sorradile.
