The trail eventually climbs the tuff boulders and enters a small valley of pine trees and meadows, home to the Ciño Negro lagoon, with an interpretive sign on the shore. In spring, the pond is a beautiful reflection of clear water and vegetation associated with the valuable wetlands created by rainfall at certain times of the year. The GR-113 signposts cross a wooden footbridge over the ravine wetland and continue toward Zaorejas through the forests of the Ciño Negro ravine. The path reaches a crossroads at the top of the ravine. The Tajo Nature Trail continues to the right toward Zaorejas, and the route follows the forest track on the left.
