The Soča (in Slovene) or Isonzo (in Italian) (other names Friulian: Lusinç, archaic German: Sontig, Latin: Aesontius or Isontius) is a 138 km (86 mi) long river that flows through western Slovenia (96 kilometres or 60 miles) and northeastern Italy (43 kilometres or 27 miles). An Alpine river in character, its source lies in the Trenta Valley in the Julian Alps in northwestern Slovenia, at an elevation of 876 metres (2,874 ft). The river runs past the towns of Bovec, Kobarid, Tolmin, Kanal ob Soči, Nova Gorica (where it is crossed by the Solkan Bridge), and Gorizia, entering the Adriatic Sea close to the Italian town of Monfalcone.
Bovec (Italian: Plezzo, German: Flitsch, Friulian: Plèz) is a town in the Littoral region in northwestern Slovenia. It is the central settlement of the Municipality of Bovec. It has been traditionally part of the historic Gorizia region, but nowadays only a minority of locals share this identity, preferring to identify with the wider region of the Slovenian Littoral.
