The third day starts in the moorlands and moves into alpine desert, with fewer trees and more rocks. The highest point is the base of the Lava Tower, after which the trail descends into the Barranco Valley. More vegetation is present in this zone, especially the area just before the campsite. This area is called the 'Garden of the Senecias' which features many of the huge senecio plants. Shorter lobelia plants are also present.
