The Breitenbach has its source at Albtrauf, the northwestern steep drop of the Swabian Alb. Its main source, named Breitenbachquelle, is located about 2km (1.2mi) northeast of Gönningen and 750 metres (2,460ft) south of Kreisstraße 6729 and 736.5 m south of Barm on the northern flank of the Pfullinger Berg, a northern spur of the Barm 736.5, in a clearing to just over 500 metres (1,600ft) elevation. The spring, situated under a severe slope, is enclosed in a niche of about 5m2 (54sqft) with natural stone and is designated as a natural monument. The water rises here at the higher layer boundary of the lower Weißjura-marl to the well-layered limestone formation[citation needed]20m (66ft) below the spring, lime sinter cushions grow from the spring water through lime precipitation. A little further south and thus above the main spring there is another spring at a little above 600m (2,000ft) elevation.
Course
At the beginning, the Breitenbach, which mainly flows northwards, flows through the Selchen valley and remains in the forest until it crosses the Landesstraße383 above Reutlingen after about half of its course. Then the brook, now lined by trees and bushes, runs through agricultural land at a westerly distance from the centre of Reutlingen. After that it crosses under the Bundesstraße28 and the railway line Plochingen-Tübingen in Reutlingen.
Estuary
The Breitenbach estuary, on its last meters flowing to the northwest, in the southern part of the Reutlingen district Betzingen at the cemetery In der Au into the Neckar inflow Echaz coming from the east-southeast.
