The Southeastern Black Forest (, 154) consists mainly of the catchment areas of the upper reaches of the Danube headstreams, the Brigach and Breg as well as the left side valleys of the Wutach north of Neustadt - and thus draining from the northeast of the Southern Black Forest. To the south and west it is adjoined by the High Black Forest (, 155) with the highest summits in the whole range around the Feldberg and the Belchen. Its eastern part, the Southern Black Forest Plateau, is oriented towards the Danube, but drained over the Wutach and the Alb into the Rhine. The southern crest of the Black Forest in the west is deeply incised by the Rhine into numerous ridges. Immediately right of the Wiese above Lörrach rises the relatively small Bunter Sandstone-Rotliegendes table of the Weintenau Uplands () in the extreme southwest of the Black Forest; morphologically, geologically and climatically it is separate from the other parts of the Southern Black Forest and, in this classification, is also counted as part of the High Black Forest.
