We read two names for this location, Sorgenti Su Gologone (Springs of Gologone) and Sorgente Su Gologone (Worries of Gologone). We are not sure if the second is a typo, a local dialect word, or actually a name. The site is a series of karst springs which are located at the northernmost tip of the Supramonte di Oliena (Supramonte of Oliena). This limestone and dolomite mountain ridge is karstified and has numerous caves and dolines. It also has subterranean drainage, the water reappears in this karst spring and others. The grotte di Sa Oche e Su Ventu, in the Lanaitho valley, and the caves of S'Edera, Su Colostrargiu, S'Eni and Istettai form a cave system which is one of the biggest in Italy. They are not connected (at least until now), but they all belong to the hydrological system of the Sorgenti Su Gologone.
The springs are a series of caves which are the resurgences, connected by trail. The site is open without restrictions, but obviously a visit by night makes little sense. The different springs flow together and form a small lake between high walls of dolomitic rock with colours between emerald green, turquoise, and intense blue. Then it forms a short stream which is a tributary of the Cedrino river. In the late summer, the driest time of the year, this is the only spring of the river. With an average flow rate of 1,500 l/s, it is the most important spring in Sardinia. The main spring alone has an average yield of 500 l/s.
