Last day of approach sees us ascend steep trails in the Relenchos Valley. The approach follows the Rio Vacas which we cross many times. The river runs red with eroded silt and you'll hear boulders trundling along in it. The steepness of the valley gives way to a huge flood plain dotted with huge boulders. Thorny vegetation struggles to survive in this harsh environment.
Winds carry drifting sand punctuated occasionally by the fragrance of tiny flowers.
During the approach you will be hiking over rocky terrain with numerous stream crossings. It will be essential to take great care of your feet to prevent foot injury and blistering. Another concern will be the extremely strong sun necessitating lots of cream and a good sun hat. In the afternoon we may carry loads a short distance up the mountain before dropping back to Base Camp. Now the real work begins.
