We start at the Hotel Krainer in the centre of Langenwang and walk along the main road towards Mürzzuschlag, past the Siglhof farm, around 150 metres to the clearly visible municipal office. Here the Hochschlossstraße branches off to the right. Follow this road until you reach a junction. Keep slightly to the right here (signposted) and you will come to a motorway subway. You can also drive here by car from the town centre, there are several parking spaces available.
Immediately after the subway, a dirt track (information board) takes us straight uphill to the edge of the forest at the start of a wide hiking trail. This leads, still slightly uphill, to a clearing with a game feeding area and on to the first buildings of the defence system (wooden buildings, large meadow).
Now we walk straight uphill to the first large castle wall (still poorly visible from the meadow) and the mighty ruins.
After visiting the castle complex (please do not climb around on the historic walls!), we briefly follow our ascent path, but branch off sharply to the left downhill at the large meadow with the wooden buildings mentioned above on a somewhat narrower path (forest path, not marked, but easily recognisable) in the direction of Mürztal. At the junction with a forest path, we keep to the right and follow this path without much ascent until we reach the clearing with the game feeding area (power line) already known from the ascent.
Keeping to the left, we now head directly downhill, past the Theresienkapelle chapel, across a large meadow to a small accompanying road next to the motorway. We walk under the motorway (subway) and via Badgasse back to the main road and the starting point of the circular tour.
