In Orgosolo's Supramonte (Nuoro's county), in central west Sardinia, in a splendid mountainous area where elk trees an junipers centuries old rise majestically from the candid fractures of limestone, suddenly opens a gigantic chasm.
Known with the name of Su Suercone or Su Sercone, it is a karst hollow generated by the collapse, in a remote age, of a huge cave.
Of circular shape, more than 400m wide and more than 200m deep, Su Sercone marks astoundingly the landscape. Along the southern border there are signs of a track that consent to reach the bottom, where several archaeological rests have been found dating back to Sardinia's prehistory.
Su Sercone is the widest karst hollow in Europe and is recognised as natural monument by Sardinia Region. The woods inside it are often inhabited by mufflons.
Su Suercone can be reached only by foot by means of long splendid promenades that's to difficult to describe here: if you wish to go by yourself we suggest that you start from the track going up to
Tiscali from Flumineddu Valley near Dorgali, being sure to dispose of detailed maps to consult as the ones of the web site
http://www.pcn.minambiente.it/PCN/ . An alternative is to address to some local cooperative which organise guided excursions.
