The ascent ends at the forest track that runs along the northern slope of the mountain range between the Abla/Ohanes road and the Ragua pass. The trail turns to the left and begins a long and pleasant descent through the Abrucena oak forest, one of the best reserves of native oak forests in Sierra Nevada. Immediately, the entrance to a rural farmhouse appears on the left of the road and the milestones of Senda Sulayr, the popular long-distance trail GR-240. The milestones with the red and white marks deviate to the right, enter the pine forest and go up to the Piedra Negra Refuge. And straight ahead they continue along the forest track of the mountains to La Roza, sharing the trail itinerary for several kilometres. The foot of the sierra and the slopes of the ravines are populated with old oaks, some of which are monumental in size. In the oak forest there are also junipers, torvisco, barberries, hawthorns and honeysuckle, depending on the type of soil, providing an attractive natural ecosystem in contrast to the large populations of pine forests that abound in the mountains. The path loses height and passes through the Peña Horadada and Diablo ravines. In the thaw season, a succession of small waterfalls forms from the upper reaches of the gorges, which are beautiful threads of white foam in the geological blackness of the mountains.
