TheTrenta Valley (pronounced[ˈtɾeːnta]) is avalley in theJulian Alps in the northern part of the traditionalGorizia region (Slovene:Goriška) ofSlovenia.
The source of theSoča River and the settlements ofSoča,Lepena, andTrenta are located in the Trenta Valley. TheVršič Pass connects the valley withUpper Carniola to the east. The Soča flows generally southwest through the valley and then onwards toBovec.
The nameTrenta is ofFriulian origin and was borrowed into Slovene. The name developed from*Tridenta, meaning 'three-tooth' or 'divided into three teeth'. This reflects the geography because the valley splits into the Soča and Zadnjica valleys, and the latter is soon split again by White Creek (Beli Potok), creating three closely spaced summits.[1]
