Only three hours walking today, because we need to complete a steep ascent along Barafu wall. Slightly scary scramble up an escarpment, very narrow with sharp drop to one side. Climbed from 4000m to 4674m today. Long traverse to Karanga camp. Everyone feeling unwell, but hot lunch of chips and coleslaw which was the best all week! After a short siesta, we take a 1 ½ hour walk to a higher altitude to acclimatise, then back down to camp for the night. Hot supper of chicken and rice.
