Regional Route D starts outside the tourist information office in the spa town centre of Bad Schönau. The first few meters take us on the street alongside the spa building. The Viennese Alps route runs left past the spa building and through the park, however we take the Regional Route right of the spa and then turn right once again into Waldgasse. We follow the hiking and cycling route into the Zöbernbachtal valley, cross the Zöbernbach stream and then cross over the Bundesstraße at Ödenhof. We ascend via the paved road up to Gasthaus Triad (Triad Inn), where Veronika and Uwe Machreich offer creative, yet hearty cuisine to their guests.
After being fed and watered, we stick to the right at the next fork in the road, following the signs with the green Viennese Alps logo, past the golf range car park and continue into the cul-de-sac. Alternatively, it is possible to go straight ahead at the fork on the Teichrunde route, which meets the Regional Route once again in the forest. A sharp turn right, then we go straight along a meadow path that is marked out in orange. The path leads us into the forest, it then turns left and we follow the signs towards Krumbach on the right via a forest path. At this point we head uphill along a path marked out in orange that runs uphill along a wooded hillside, cross a rift and then turn right after a few minutes on the edge of the forest onto a meadow path. The meadow path continues with views of Krumbach Castle up to Gehöft Dirndlhof. We then carry on the adjoining Dirndlbauer track to Hof in Egg, where we turn left onto a road and follow the blue signs slightly downhill with views of Krumbach and the Rosenkranz Chapel. After a brief break at the chapel, the final stages of Regional Route D carry on down the road, which turns into a wider road at a hairpin bend. We keep left and continue to walk downhill towards Krumbach, and Tiefenbachstraße takes us to the centre. On the right-hand side we have views above the municipal office, the bus stop, and therefore also the end of Regional Route D in the Marktstraße. The Museumsdorf (museum village) is well worth visiting, and it is located somewhat south of the town centre following the B55. Alternatively, it is possible to extend the hiking route by adding Regional Route C from Rosenkranz Chapel to Kirchschlag. In Kirchschlag the main Viennese Alps route heads on to Bad Schönau. In Krumbach buses travel either to Edlitz-Grimmenstein railway station or back to Bad Schönau.
