The trail goes down the side of the valley to a clearing where the cliffs that form El Estrecho del Río Trabaque appear. And right in front of it, the visor of a calcareous cliff that flies over the valley is striking, is El Picayo, the place that gives its name to the trail and an important crossing point on the trail route. The path seems to go down to a dead end, you have to pay attention to the marks on the trees and the route of the path to the bed of the Trabaque river. The fording of the river does not present any complications except in the season of heavy rains, when it is full of flow and it may be necessary to get your feet wet. The trail is old and little used but continues very clear from the edge of the ravine, the slope is steep and there is no other way out of the canyon. In a hole in the trees there is a post for PR-CU 25 below El Picayo.
