From Freiburg, the route passes through Stegen, Buchenbach, Hinterzarten, Titisee-Neustadt, Kappel (part of the municipality of Lenzkirch), the Wutach Gorge, Blumberg, Engen and Singen.

Because the path cuts across the Black Forest, and then continues across the volcanically formed Hegau region before skirting Lake Constance in its final section, it offers a great variety of landscape and vegetation.

The route is very well marked throughout its length, using a waymark of a red and white lozenge (divided vertically, and with its longer axis horizontal) on a yellow background.

According to Bremke (1999), the original planners of the route intended that the red end should always point towards Konstanz and the white towards Freiburg; this rule is generally but not universally obeyed in the waymarking in place as of 2007[update].

The Querweg intersects all three of the main north–south Black Forest long-distance paths, the Westweg at Titisee, the Mittelweg at Hochfirst, and the Ostweg at Achdorf.
