We asked the policeman at Ollague township if it was OK to drive up yonder Volcano. He simply shrugged in dismissal of such an odd question. So we began from the plain at 3720m altitude and picked our way up the unmaintained, rock strewn track up the western flank of Volcan Ollague. We camped at 5100m altitude on a tiny offshoot at the end of a hairpin bend on a ridge - so as to avoid any boulders the Volcan might send hurtling down. After a breathless night we continued our drive up to 5350m until the rockfalls were too thick - and we walked. A further 200m vertical and return in 2hrs. Awesome! map
