In Radmer, shortly before the Greifenberg Castle 889 m, the marked hiking trail No. 668 leads largely through forest, finally over exposed places secured with ropes to a saddle called G`spitzte Stein 1555 m. Here you enter the Gesäuse National Park. At the G'spitzten Stein we are impressed by the view of the Lugauer, which could also be climbed on the continuing path No. 668. We walk northwards for about 15 minutes over alpine meadows to Haselkar. Here we wonder about mysterious remains of stone buildings, about 200 meters south of the hut. Like ruins in Colombian Peru, they stand on a small plateau directly in the Lugauer Plan.
We walk back the 15 min. and choose the trail to the southwest, which leads first briefly uphill, then slightly downhill to the Neuburgsattel 1439m. The path splits here, you may also descend to Johnsbach. We hike over the beautifully situated Neuburgalm where we can take a leisurely refreshment, in an easterly direction back to Radmar, where we also pass the copper mining museum. Here we turn left towards Radmer/Hasel and cross the small bridge to the end of the trail. The road takes us past the dilapidated castle to our starting point.
