It spans the area from Volčanski Ruti in the south to Borjana and Žaga in the west, north up to the Vršič Pass, with the northernmost settlements being Strmec na Predelu and Trenta.

Larger settlements include Volče, Volarje, Idrsko, Drežnica, Kobarid, Borjana, Srpenica, Žaga, Bovec, Čezsoča, Soča, and Log pod Mangartom.

The consonant *g turned into ɣ and into voiced h at the end of a word or partially spirantized into ǥ.

[8][9][10] The Soča dialect retains neuter gender in all numbers and the dual still exists, but it is used inconsistently.

[11] A dictionary of words used in the northern microdialects, particularly in Bovec, was written by Barbara Ivančič Kutin in 2007.
