Yvette and Michel Vaucher made numerous significant climbs in the Alps throughout the 1960s and 1970s, including Piz Badile, the Aiguille de Triolet, the Aiguille du Dru, the Eiger, the Große Zinne and the Grandes Jorasses. In 1966, they made the first direct ascent of the north face of the Dent Blanche. They climbed frequently with Loulou Boulaz and her partner Michel Darbellay.
