The Colhi Rubri (direct translation from Vallo to English: Red Hills) form a spur mountain range west of the Montes Aemili of which it is a part. The range stretches north along the Vhallonese coast into the center of the Xhlavonia Peninsula. To the west of the range is the Atlantic Ocean. They take their name from a translation of the Visenti word for the area, so called for all the blood spilled on them. A large part of the mountain range is protected from development by law.
