Between 1929 and 1931, the Schierstein NaturFreunde built a Naturfreundehaus in log construction style, the Heidehäuschen, with kitchen, event room, accommodation options, and a room for housing a scientific collection in the 'Stadtwald Wiesbaden Schierstein', the Freudenberg, in around 4,000 hours of voluntary work. The Heidehäuschen was confiscated in 1933, and the painstakingly assembled scientific collection was destroyed by the SA. The NaturFreunde were prohibited from entering the area, which then became overgrown and the building fell into disrepair.

In 1955, the new Heidehäuschen was inaugurated, which, with several extensions and modifications, is still used today as a clubhouse and accommodation especially for children and youth groups. Here at the Naturfreundehaus, we cross the Freudenbergstraße at the pedestrian crossing and reach the entrance of Schloss Freudenberg. Built in 1904 by architect Paul Schultze-Naumburg, the castle, actually a representative villa, was inhabited only until 1908 by its builder couple James Pitcairn-Knowles and Marie Eugénie Victoria Guérinet. Afterwards, the district of Essen used the property as a children's home. During the Third Reich, the castle belonged to the 'Lebensborn' until 1939, an association aimed, among other things, at promoting the birth rate of 'Aryan' children, including through extramarital relationships. After the war, the American forces took possession of the castle. Later it increasingly fell into neglect until the castle and park were taken over and developed by the Society for Nature & Art as a 'field of experiences of senses and thought'. A visit allows one to experience and examine one’s own perception.

We walk around the castle, down through the park, and reach a field path, which we take to the right. The path is marked as an access route to the 'Rheinsteig'. It then turns left toward the 'Apfelweinstube zum Himmelreich'. Upon arrival, we walk around the property and descend a steep grassy path. Reaching an asphalt path, we turn left and proceed downwards. Here we reach the 'Rheingauer Rieslingpfad', marked with a wine glass, and stay on this path towards Schloss Biebrich (the route also follows the Hessenweg 7 [H7] to the Schiersteiner harbor). This path initially leads through vineyards, orchards, and allotment gardens into the Lindenbachtal valley. We are near the A66 motorway, which we must pass under. At the Wiesbaden-Koblenz railway line, we turn right and immediately back left through the railway underpass. Now we walk along the Lindenbach stream, cross Söhnleinstraße, and reach the so-called 'Lindenviertel' of Schierstein. The street 'Am Lindenbach' leads us directly to the Schiersteiner harbor. Today, the harbor is a water sports center and recreational area for Wiesbaden and the region. Directly on the harbor promenade in the Wilhelm-Loos park is a replica of the Schiersteiner Jupiter column, a monument of Roman god worship. It was discovered in 1889 during construction work on the lower Freudenbergstraße at a depth of 5 meters and dates back to 221 BC. The original is kept in the Wiesbaden museum.

We go right and circle the West harbor, home to the local water sports clubs. During the harbor circuit, we reach the Dyckerhoff bridge, which spans the harbor entrance and, since 1967, has enabled walking around the Schiersteiner harbor. The bridge was a gift from the Dyckerhoff company on the occasion of its 100th anniversary and is a much-admired construction and landmark of Schierstein. From the bridge, there is a magnificent view of the Rhine, harbor, Schierstein, Taunus, as well as Biebrich, Mainz, and the Rheingau. At the harbor entrance is the DLRG rescue station.

We continue along the Bismarcksaue towards Biebrich, passing under the Wiesbaden–Mainz motorway bridge. The path then follows the Rhine, with views of the Rettbergsaue and its recreational area. Over a plane tree avenue, we reach Schloss Biebrich, located directly on the Rhine. From the staircase, there is a beautiful view of the Rhine. Schloss Biebrich was built modeled after Versailles. Constructed in stages from 1700 to 1744, it is today one of the most important baroque palaces on the Rhine. Once the residence of the Nassau dukes, the castle is now mainly used for representative purposes by the Hessian state government and is also the seat of the State Office for Monument Preservation Hessen. We enter the English landscape-style castle park on the east side of the castle. In the castle park—located directly on the pond—the Mosburg was built in 1806. It is an artificial, romantic ruin where the Biebrich local museum was once housed. The park is also home to wild-living Alexander parrots, which can be well observed in the tall trees. We leave the castle park through the north gate, cross Äppelallee, and pass through a railway underpass beside a restaurant into the so-called 'Gibb,' known for the annual 'GibberKerb' festival held since 1909 in the Mosbachtal. In the Gibb, we walk through the Bachgasse, Bleichwiesenstraße, and reach Tannhäuserstraße, which we take right to Gabelsbornstraße. There, we go under the motorway underpass and immediately turn right onto a pedestrian path leading to Volkerstraße. Upon arrival, we walk a short distance left and find ourselves opposite the Richard Wagner park. Through the small but beautiful park, we reach the Biebricher Höhe and Biebricher Allee. Here we stand directly opposite the reception and administration building of the Henkell sparkling wine cellar. On our side, to the left, is the Landesdenkmal for Adolph, the last Duke of Nassau and Grand Duke of Luxembourg. It was erected in 1909 by a citizens' initiative. From there, there is a beautiful view of the Rheingau and the Rhine valley.

Here we end the first section of the anniversary circular route 'Around Wiesbaden'.
