As day breaks we ascend above the tree line onto rockier ground. Beautiful views of the Glacier Condor and surrounding peaks unfold as we make our way to the John Gardner pass (1200m). The views from the pass are simply jaw dropping as the immensity of the Grey Glacier and Southern Patagonian Ice field lie before us. The descent is long but the views are stunning, the trail takes us down beyond the snout of the glacier to the shores of Lake Grey and our rest stop for the night.
