Tips from the Community
Incredibly beautiful view and you can quickly gain a lot of altitude. ⚠️ Attention: many vehicles also drive here in the pre-season and overtake even when there is oncoming traffic.

Great view of the rocky landscape of Isola Rossa and the beaches 😊. If you come by bike, you should definitely note that you can't just roll down the beautiful descent, as there are always speed bumps installed. Some caution is required here - also because of the narrow paths and the traffic.

In the Middle Ages it was part of the Giudicato of Torres, in the Curatorship of Anglona, and from the thirteenth century it was ruled by the Benedictine monks of Montecassino. At the fall of the Giudicato (1259) it passed to the Doria, the Malaspina and later (mid-14th century) to the Aragonese. The Doria built two important castles near Bulzi and Perfugas. In the eighteenth century the town was incorporated into the Principality of Anglona, first under the rule of the Pimentel and then of the Tellez-Giron, to whom it was bought back in 1839 with the abolition of the feudal system.

The surface area of the lake is 400,000 km² with an average depth of 20 metres. The water quality is not the best because the lake is located between fields and pastures and therefore receives high concentrations of nutrients (phosphorus and nitrogen) from agriculture. At the mouth of the Monte Ruiu gorge towards the sea are the thermal baths of Casteldoria, from whose springs water gushes that reaches a temperature of 70°C, whose properties were already known to the Romans who passed through Anglona.

Lake Casteldoria is an artificial reservoir with a capacity of about 8 million m³ of water for almost exclusive hydroelectric use, created by artificially damming the Coghinas river with the construction of a dam in 1956. It is located at the foot of Mount Ruiu. The lake is not only fed by the river, but is also hydraulically connected to the larger and more famous Lake Coghinas.
