In order to aid our acclimatisation, we have an extra night at Shipton's, from where it is possible to complete a series of short walks on the summit circuit. Today’s trek will see us ascend to Hausberg col (4700m), then descend steeply to Hausberg Valley and Oblong tarns before returning to Shipton’s in time for lunch. Hiking high and returning to sleep low offers a good boost to acclimatisation.
