The best walk of the week and probably some of the best walking you can have in the Massif Central, with breathtaking views all along the way. A mix of easy walking and challenging terrain, with bits of scrambling here and there, including the (in)famous Brèche de Rolland and a tricky bit S of Pic de Bataillouse. The best part of the walk was arguably the ascent of Puy de Peyre Arse (lovely name, isn't it ?) and the exploration of its fantastic N ridge, which is slightly airy in places. 7 summits climbed for my challenge, i.e. a total of 21 for the week. Main summits: the amazing but very popular Puy Mary (1783m) as a starter, then along the ridge to Puy de Peyre Arse (1806m) and Puy de Bataillouse (1683m).
