This hike on Regional Route T starts at Myra Falls in Muggendorf. The conservation charge as an entrance fee is € 3.50 for adults and € 1.00 for children. We follow the cascades of Myra Falls over steps and bridges, enjoying the full splendour of such a natural sight. At the top of these wild waterfalls, Viennese Alps trail signs lead us away from the water and we ascend left towards Haussteinswiese. A detour to the Hausstein vantage point grants us views up to the Schneeberg.
We cross the northern edge of the Haussteinwiese and follow the hiking route downhill to Gasthof Karnerwirt. Directly opposite, we follow the narrow path alongside the Myrabach stream (also known as Wallfahrerweg) and avoid a stretch of road in the process. We come back to the road after a few minutes, stay along the edge of the road heading towards Thal, then turn right onto Atzerstraße (also marked in red and is path no. 231) near the Feuerwehrhaus. We turn left at a small car park into the Viehgraben ditch heading towards Kieneck. At this point we now walk slightly uphill in the Viehgraben, until we take the fork to the Matrassteig path after around 40 minutes of walking. After several hairpin bends and steeper sections, we reach the summit of Kieneck. The sun terrace on the Enzianhütte cabin to our right is a splendid place to rest.
We continue to hike along Regional Route T and reach the next destination, namely the Unterbergschutzhaus, which is on the route of several long-distance hikes. From the Enzianhütte cabin, we head downhill with wonderful views of the Bettelmannkreuz, then start ascending once again. After going past Kirchwaldberg, we follow the hiking path going both uphill and downhill. We cross the first pistes of the natural skiing area on the Unterberg and reach the Unterbergschutzhaus, in which it is possible to stay overnight. A splendid view can be seen of the summit of the Unterberg.
Regional Route T now leads past the small Maria Einsiedl Church and heads through the Miragraben ditch downhill to Grieshof. At the same time, we’re also on the Wiener Mariazellerweg route (marked in red, and path no. 06). From the Grieshof, we follow the paved road down the valley along the Rainbach stream. Shortly after the crossroads at Klauswirt, we veer somewhat left from the road and hike up a trail that is parallel to the road in the direction of Rohr im Gebirge. After walking around 20 minutes, we come to the road once again and follow it to a bridge. We then hike left over the Klausbach stream and reach the centre of Rohr im Gebirge in a few minutes. There are places to stay overnight in Rohr im Gebirge. Buses travel from Rohr im Gebirge to Payerbach-Reichenau railway station or to Schwarzau im Gebirge.
