Vertex located next to the antennae. A perfect place for a sandwich, especially if you continue 100 meters towards "Los Cañones", to the meadow below.

SPECTACULAR VIEWS from this cave accessible by a small climb (with a chain) and 10-20 meters through a cave no more than 1 meter high in some sections. An enjoyable site. Although yes, be careful if the ground is wet
