It is located to the side of a path close to the village of Regoufe, in the parish of Luou. It is signposted and is on the PRG-238, Teo petroglyph trail. 

Outeiro del Cuerno is one of the most exceptional petroglyphs in the Municipality of Teo. The importance of the panel stems from the fact that it has a representation that is a very scarce type within Galicia. The central motif is a figure of almost square shape, designed with double stroke. At the upper end, there are six small circles in a row, and the inner space of the square is occupied by a zigzag line that divides the motif into 7 horizontal strips. To the left of the figure is a weapon, most likely a dagger, judging by the small size, with the tip down. According to some authors it could be a highly schematic human representation of a powerful individual, probably a warrior, accompanied by some of his attributes (dagger, sword or halberd). In a lower area of the rock, separated by a natural crack, also appears the fairly eroded figure of a quadruped looking to the right, of which it is not possible to identify the species. 

The best time to observe the principal motif is in the early morning and late afternoon.The remaining figures are more weathered and are appreciable particularly at night with the help of artificial light.
