From Pian Marchisio I followed the valley up to Gias Gruppetti, then offtrack I went to the Brignola-Seirasso pass, and from there to the Cima della Brignola & back. Later I also reached Cima Frelette through the lakes and the Bocchino della Brignola. In the last part of the hike I climbed Cima Seirasso through Peak 2367 and Monte Pra Canton, closing the walk to Pian Marchisio.
