Dreitannenriegel, Mountain viewpoint in the Bavarian Forest, Germany

Dreitannenriegel is a 1,090.2 m high mountain in the crest of the Anterior Bavarian Forest, in the Alberting district of Grafling above Deggendorf. At its summit stand a large summit cross with a summit register and a display board explaining the panorama over Lower Bavaria. The summit and much of its slopes belong to the Deggendorfer Vorwald protected area.

The Dreitannenriegel lies in the Alberting cadastral district of the municipality of Grafling, in the crest of the Anterior Bavarian Forest above Deggendorf. Its summit and a large share of its slopes belong to the Deggendorfer Vorwald, a Special Area of Conservation under the EU Habitats Directive. The mountain is named alongside the Breitenauriegel, Geißkopf and Einödriegel as a neighbour in this ridge.

The summit cross carries a summit book, and a display board explains the panorama over large parts of Lower Bavaria. Paths reach the top from Grafling, Gotteszell, Habischried, Bischofsmais and Rusel, so walkers arrive from several villages. The mountain lies in the Gemarkung Alberting of the municipality of Grafling.

The climb from Mietraching follows marked trails and takes about 45 minutes with proper hiking boots as a necessity. The path crosses varying terrain, so sturdy footwear helps ensure a safe and comfortable walk.

The summit cross stands beside a display board that explains the panorama over large parts of Lower Bavaria. The board is the detail to look for: it names what lies below, from Deggendorf to the ridges of the Anterior Bavarian Forest, before the Alps appear on föhn days in autumn.
