The route begins through a grove of rowan pine trees and through the historic area of Los Pozos de Cartagena, Orihuela and the Villa, until arriving at the Collado de los Pozos de Don Eleuterio. Positioned in dense forest, we soon will see a path to the left by which the ascent is made in the last section of the route. At the moment we will continue straight ahead, with a gentle slope, to cross the elongated plateau to reach the summit of Pedro López.
From the summit descend to the Humero pass, a place where the access to the mythical valley of Malvariche (on the right, but not taken) or to El Pinillo and the caves of La Plata (to the left, which is followed) are distributed. Both at the top of Pedro López and in these areas it is common to find arruí or mouflon, wild sheep of the Atlas. Catch sight of the flight of some great and majestic birds of prey like the golden eagle or griffon vulture.
After descending through the El Pinillo forest track, which covers a large area, turn right onto a path that passes through the ruins of the houses of Don Blas and La Carrasca. This will be a good place to take a break and walk the ascent to the pass of the Pozos de Don Eleuterio by the link PR-MU 63.1 or Prado Negro path. Once on the Eleuterio pass, follow the path on the right (previously used in the first part of the route) to return to our starting point, the Mangueta pass.
The altitudes above 1,300m and the abundant shadows of the first part of the route made it possible that between the sixteenth and nineteenth centuries nothing less than 26 Pozos de la Nieve were built. They were used during the winter to enclose snow, after it was crushed and turned into ice and cut into blocks. They were transported down into the valley on beasts and sold in the cities of Murcia, Cartagena, Lorca and Orihuela for health purposes or domestic consumption among wealthy families. They are of unique historical-environmental heritage, as there is no other Mediterranean mountain known to have such a high concentration of buildings devoted to the production of ice.
