Pení, Mountain summit in Cap de Creus, Spain.

Pení is a mountain summit in the Cap de Creus area that rises to about 607 meters. From the top, views extend across Cadaqués Bay, the Bay of Roses, and the surrounding coastal landscape of northeast Catalonia.

During World War II, an American reconnaissance aircraft crashed on the slopes during a mission toward southern France. The United States military later established a radar station at the summit in 1959, which the Spanish Air Force now operates.

The name Pení has no agreed origin: Celtic, Greek, Latin and, more recently, Hebrew roots have all been proposed. The summit is occupied by the EVA-4 air surveillance radar squadron of the Spanish Air Force, a station built by the United States in 1959, so the installation itself is not open to visitors.

The area is accessible via marked hiking trails from Roses or Cadaqués, with spring and autumn offering the most favorable conditions. The hike takes several hours and requires good fitness and sturdy footwear for the rocky sections.
