A 7km round trip from Kobarid, the vigorous hike up to the ancient settlement of Tonocov Grad takes you through the forested hills of the Upper Soča Valley. Dating from the 5th Century, Tonocov Grad, perched on a 400 metre high hill, is well placed for sweeping views across the valleys below. For the return leg, you can follow one of the trails or minor roads that hug the scenic Soča river, taking in the remains of WW1 fortifications as you go.
