The Soča river basin is an expansive and diverse land. It stretches from the Alpine north to the lowlands in the lower reaches of the river, and also takes in the Idrijca and Vipava valleys and all the other tributaries.
The territory is administratively incorporated into the Northern Primorska – Gorica statistical region, which today comprises 13 municipalities: Bovec, Kobarid, Tolmin, Kanal, Nova Gorica, Brda, Šempeter – Vrtojba, Miren – Kostanjevica, Renče – Vogrsko, Ajdovščina, Vipava, Idrija and Cerkno.
One of the key developmental orientations of the region is for tourism to be developed across the entire area, services and attractions to be linked together and a common destination established. This destination is named the Emerald Trail, after the Soča River – the biggest natural and symbolic feature of the area.
