The fourth day starts with the ascent of the Barranco Wall, which is considered a scramble in climbing terms. The top of the Wall has attractive vistas of Kibo and the surrounding landscape. The trail continues with many up and down sections across small streams and rivulets. It follows the path up and across a rocky zone, finishing at the high camp Barafu. Very little vegetation can be found on the inhospitable terrain. A field of sedimentary rocks litters the ground like many broken mirrors.
