They go low, so we go high. We drove south past Laruns into the mountains up to the Lac de Bious-Artigues at 1400m altitude. We were shocked, shocked I tell you, to find the car park by the lake full, with well-equipped and, worse – fit-looking – hikers setting forth. We were most aggrieved, having had the forests and mountains to ourselves the previous two days – well, except for the cattle and horses, but they didn’t clog up the paths, they weren’t smugly thin and they didn’t have hiking poles and expensive walking gear.
