Our 10.5-kilometre hike is marked no. 3. It starts at the Hainsberg-West S-Bahn station or opposite the road at Heilsberger Park. From here, we walk to the southern steep slope of the Weißeritz valley and follow the "Grüner Strich" hiking sign behind the bus stop up towards Opitzer Höhe. After approx. 1.3 kilometers we reach our first sight, the Backofenfelsen. The Backofenfelsen, which geologically no longer belongs to the Ore Mountains, towers about 50 meters above the Weißeritz valley floor near Hainsberg. Several benches invite you to linger. The Backofenfelsen is a natural geological monument whose rock is dominated by Rotliegendes and a conglomerate of porphyry and granite. The caves in the rock were formed by erosion and weathering. As early as 1752, the cave by the road was referred to as a "baking oven".
From here, we continue along the Förster-Claus-Weg to the Opitzhöhe, which offers a beautiful panoramic view. Since 1995, a wind turbine on the Opitzhöhe has been a clear landmark. The main "Grüner Strich" hiking trail continues to the right in the direction of Weißig and Pesterwitz. We follow no. 3 to the left along a field path towards Tharandt. This continues to offer beautiful views in all directions. At some point, we see a sign to Johannishöhe on the left of the path. However, we continue along Hohe Straße, marked no. 3, past a garden plot and on to Opitzer Weg into the valley. Almost at the bottom, we turn left into the street An der Schmiede, which we follow to the church. Then continue along Roßmäßler Straße to the market square. There are public toilets at the town hall. The small town, first mentioned in 1216, has a striking viewpoint over the town with its medieval castle complex. There are several places to stop for refreshments here in Tharandt.
From the town hall, we walk left along the Schloitzbach stream. On the right-hand side we see a net parking lot. Opposite, on the left-hand side of the road, the Brüderweg begins, leading uphill into the forest. Caution! Some parts of the path are exposed, and due to the steepness of the slope, parts of the path are often buried or break off, so surefootedness is required. The Brüderweg is no longer an official hiking trail. It is partly secured with iron ropes. Every now and then you have to cross a stream. Nevertheless, the path high up on the slope is highly recommended due to the beautiful natural surroundings. When we reach the hiking signs, we see that we were already here at the start of our hike and walk back to the starting point.
