The Ohlsbach Formation is a geologic formation in Germany. It preserves fossils dating back to the Gzhelian stage of the Late Carboniferous period.

Mariä Krönung (Coronation of Mary) is a Catholic pilgrimage church in Lautenbach, Baden-Württemberg, Germany, where pilgrimage to a miraculous image of Mary was documented in the 14th century. The present church was built in the 15th century in Late-Gothic style, a home for Premonstratensian friars from a dissolved monastery. Mariä Krönung is a significant cultural monument in southern Germany, because it retains many original Gothic features, such as the rood loft and fused stained-glass windows. It has been the parish church of the village since 1815.

Lautenbach (Low Alemannic: Luddebach) is a municipality in the district of Ortenau in Baden-Württemberg, Germany. It has a Gothic pilgrimage church, Mariä Krönung.

The All Saints Waterfalls (German: Allerheiligen-Wasserfälle) are located in the Black Forest on the territory of the town of Oppenau in the German state of Baden-Württemberg at an elevation of about 500 m above NN. The Lierbach stream, also called the Grindenbach, cascades, as a natural waterfall, down seven steps, a total drop of 83 metres. Due to the scouring of the rocks under the cataract which have formed basin-like holes known as Gumpen or kolks), the falls are also called the Büttensteiner Waterfalls ("Tub Stone" waterfalls) or Sieben Bütten ("Seven Tubs").

The Moos is a mountain range in the Central Black Forest in southern Germany. Its highest points are the Siedigkopf (877.5 m above sea level (NHN)) and the Mooskopf (871.2 m above NHN), actually the Geisschleifkopf. The Moos is the local mountain or Hausberg of Gengenbach and Oppenau. The Moos separates the valleys of the Rench and the Kinzig in an east-west direction. At the same time the Nordrach valley and theformerly free imperial valley of the Harmersbach rise on it and flow in a north-south direction. Due to its formerly dense and dark afforestation, the Moos is the scene of numerous legends and legendary figures. A leading character that appears time and again is the Moospfaff, an old monk from All Saints' Abbey, who on his way to an extreme unction lost the host and now searches around leads people astray whilst he tries to find the host. The fictional character Simplicius Simplicissimus, who is commemorated on a monument, from the novel Der abenteuerliche Simplicissimus by Hans Jakob Christoffel von Grimmelshausen, lived for several years on the Moos during the Thirty Years' War. There is an observation tower, the Moos Tower (Moosturm), on the Mooskopf which was erected in 1890 and is maintained by the Black Forest Club.On the Geißschleif Saddle between the Mooskopf and the Siedigkopf is the junction of three trails: the Kandelhöhen Way, Gengenbach–Alpirsbach Black Forest Trail and the Rench Valley Trail. On the Kornebene (640 m above NN) the Friends of Nature's Gengenbach branch run a managed hut (Kornebene Friends of Nature House) with overnight accommodation. In the municipal territory of Nordrach at a height of 589 m is Gasthaus Moosbach, the highest inn in the county of Ortenau and the whole of the Moos hills. On 26 Dec 1999, Hurricane Lothar caused serious damage on the Mooskopf and Siedigkopf. Hitherto the summits were densely covered with high spruce and fir trees which largely blocked the view from the observation tower. After the storm had destroyed the trees, instead of the old monoculture, a considerably more varied mixed forest emerged. On the Siedigkopf is a monument that commemorates the hurricane.

The Lothar Path (German: Lotharpfad) is a forest experience and educational path in the Schliffkopf Nature Reserve by the Black Forest High Road between Oppenau and Baiersbronn on the B 500 in the Northern Black Forest. The name of the windthrow educational trail is derived from Hurricane Lothar, which tore through the forest here on 26 December 1999 with wind velocities of up to 200 km/h creating a wide swathe of debris. After mountain pastures became increasingly uncultivated as a result of the housing of livestock and the abandonment of haymaking, the plateaux of the Northern Black Forest were initially reforested, predominantly with spruce, whose roots could not penetrate the bunter sandstone soil to any great depth. As a result, when the storm hit the state of Baden-Württemberg, around 30 million cubic metres of wood was torn from the ground within the space of two hours. After the storm, conservation and forest managers decided to leave the 10-hectare windthrow area of the Lothar Path to recover unaided as an area of protected forest or Bannwald, in order to be able to observe the long-term, natural regeneration of the habitat. The project was entrusted to the Black Forest National Park. In June 2003, as part of the EU-sponsored Grinde Black Forest project, an 800-metre-long educational and discovery path was constructed by the Black Forest High Road (B 500) between Ruhestein and Kniebis-Alexanderschanze. The path runs along steps, bridges and footbridges made from the dead wood, over and under the fallen trees. An observation platform offers views over Braunberg, Lierbach, Oppenau, Strasbourg and the Vosges; in clear weather, the Feldberg, the Kaiserstuhl and the Alps may be seen. In 2007 it was recorded that nearly 50,000 visitors came to the Lothar Path annually.

All Saints' Abbey (German: Kloster Allerheiligen) was a Premonstratensian monastery near Oppenau in the Black Forest in Baden-Württemberg, Germany. It is located at 620 metres above sea level in the upper valley of the Lierbach.

The Schliffkopf is a mountain in the Northern Black Forest between Baiersbronn, Ottenhöfen and Oppenau. It is 1,053.6 m above sea level (NHN). The Schliffkopf lies on the Black Forest High Road in the National Park and is the site of an eponymous four-star "wellness" hotel. Various long-distance paths, including the West Way, run over the Schliffkopf. At the end of June 2003 a nature trail, the Lothar Path (Lotharpfad), was opened at the Schliffkopf on the topic of storm damage. Along an 800-metre-long educational and experience trail, visitors can see how this ten-hectare area, heavily damaged by Hurricane Lothar in 1999, has gradually recovered and been recolonized. The Lothar Path runs along footbridges, ladders and steps and shows how the forces of nature act, how nature deals with destruction in such an area and what naturally regrows. The Schliffkopf is a source region for the Acher and the Murg.

The Karlsruher Grat is a mountain ridge approximately 400 m long, situated near Ottenhöfen in the Black Forest in Germany. An alpine route with a climbing section passes along it. It is considered the only via ferrata in the Northern Black Forest.

Schauenburg Castle is a ruined hilltop castle located in Oberkirch, Germany, atop a 367-metre-high (1,204 ft) (NN) hill spur overlooking the Rench river valley above the town of Gaisbach, Baden-Württemberg. The castle was built by Duke Berthold II of Zähringen.The well-preserved ruin includes the remains of two towers with living quarters, a gate tower, a rampart, and a shield wall with an attached chapel. The remains of an outer bailey are surrounded by a dry moat and a second shield wall. The castle is now a tourist attraction and includes a small museum in the cellar of the former castle chapel and a restaurant.

The Acher Valley Railway (German: Achertalbahn) is a 10.4 km long branch line from Achern to Ottenhöfen im Schwarzwald in the Black Forest in Germany that branches off the Rhine Valley Railway.

Ottenhöfen im Schwarzwald (Low Alemannic: Oddeheefe) is a town in the district of Ortenau in Baden-Württemberg in Germany.
