We visited Ref. Manganu and I took the opportunity to scale the nearby Capu on the way back to Poppaghia.
Very instructive viewpoint, but regarding the shape of this hill it is more a small, not to prominent elevation in the Serra San Tomaghiu... just a walk. The most challanging part is the rocky section above the Bergerie de Colga.
Hiked to Lac de Nino, circled it and headed for Capu a u Tozzu. Good views, fine weather.
