Puig Neulós, Mountain summit at French-Spanish border, France and Spain

Puig Neulós is a mountain summit on the French-Spanish border that rises to around 1,257 meters (4,125 feet) elevation. Its rocky surface is composed of crystalline schist, slate, and phyllite that give the peak a rough, dark appearance.

The name appears in a 1322 text as Podio Nebuloso, Latin for a rounded summit covered in clouds. The crest formed the border between the counties of Empúries and Rosselló, and since the Treaty of the Pyrenees in 1659 it has separated Spain and France. A border-marking commission received a Spanish complaint that the boundary stones near the summit had been shifted a few metres by the French relay antenna; the dispute remains unsettled.

The name is Catalan, recorded in Latin as Podio Nebuloso in 1322, meaning "cloudy summit". The summit carries a pyramidal stone monument, the Torre d'en Manel, first built by Manel Costa in the late 19th century, destroyed when the communications station was installed and later rebuilt. The Albera cow grazes freely on the slopes, which is why a fence runs along the ridge.

Reaching the summit requires good physical fitness and sturdy boots due to steep terrain and rocky surfaces. Several marked hiking routes approach from different directions with yellow paint blazes making the trails easy to follow.

The lattice tower near the summit is a TV and radio transmitter serving Roussillon, with signal spilling into northern Catalonia; it is not a military installation. Spain has complained to the border demarcation commission that its construction shifted the boundary stones by a few metres, and the dispute remains unresolved. The pyramidal stone monument beside it, la Torre d'en Manel, was first built by Manel Costa in the late 19th century, demolished when the station went up, and later rebuilt.
