Tolmin, the town that gave the name to the entire region, is the largest settlement in Zgornje Posočje (Upper Soča Valley) as well as the economic, cultural and administrative centre of the valley. Its streets and houses bask in sunlight on a terrace above the confluence of Soča and Tolminka rivers. It is positioned at the right distance from the steep mountainous valleys, so that inhabitants may enjoy mild winters, and from the sea and Gorica plateau, so that they may take pleasure in enjoyable summers. This section includes the area of valleys and mountain villages above Tolminka and Zadlaščica, and continues through the hinterland of Volče and Čiginj all the way to the state border on Kolovrat.
