At the top of Puig Alt are the remains of a small rectangular building, which, due to the excellent views the location offers and the architectural similarities with a building near Puig Marès, is thought to be part of a network of watchtowers, for the prevention of the constant danger that piracy represented to the coast in medieval and modern times.

Enjoy these 360º views across the harsh (due to the wind and the sun), damaged (by wildfires) and transformed (by man) landscape of Cap de Creus.

In front of this, there is Cap Norfeu (also a Integral Nature Reserve inside the Natural Park). On the left is the Vall de Jóncols, which forms a cove of the same name on the north side of Cap Norfeu; in front and to our right, is the Vall de Montjoi which also forms a well known cove to the south of Norfeu. At the head of the Vall de Jóncols, is the peak of Pení mountain (608 m) where there are the radar station facilities (Air Surveillance Squadron number 4, EVA-4) belonging to the Spanish Air Force, built by the United States in 1959.

We will be walking across silica materials, principally slate and schist, occasionally coming across limestone rock that is transformed into quartzite and white marble.

Notice that on the rocks there are some beautiful orange lichens. These are some of the many lithophytic lichens (growing on rock). They are an association between an algae and a fungus, neither of which could live separately. They are indicators of changes in the environment (contaminants, temperature, etc.).
