Camp at Karanga Valley (4000m)

Today several groups have given up because of AMS (Acute mountain sickness).
But all our group is ok (except ponctual light headach for some of us,
normal at this altitude).
We just have lunch in our camp settled at Karanga Valley (4000m) after
having scrambled Barranco wall (4330m). Now everybody is going to
sleep a bit before diner :) ...
