Solo. From La Sage, Villaz. Along road, tracks and then paths via Mayens de Cotter to Col de Torrent. I went up the SE ridge, keeping near the crest, to reach the summit of Sasseneire. The last part is somewhat loose and exposed. I returned the same way more or less. A lot of people and children going up to Col de Torrent but nobody else was ascending Sasseneire. Weather good, but it started raining near the end.
