1st stage: (6.3 km)
We follow the Harzklub signs with the yellow square waymark to the Carlshausturm.
From the starting point at the tourist information office, the path leads approx. 300 m to the station of the Harzer Schmalspurbahn (locomotive exhibition).
To the left of the bridge, the city of Hasselfelde honors Dr. Hermann Blumenau, founder of the city of Blumenau in Brazil, with a monument.
We keep to the right here and turn right again behind the hardware store in the direction of the forest lake pool and Rotacker.
A beautiful forest path (1.1 km) now leads us to the barbecue area with a historic charcoal burner's hut and after another 300 m we reach the forest lake pool of Hasselfelde.
Along the pool and Hoyerteich we cross the B81 after about 350 m into the Rotacker housing estate.
We follow the yellow square through the residential area, turn right once and arrive at the forest parking spot Ferienpark Blauvogel.
From here we turn left into a spruce forest. Then, after about 200 m, we continue to follow the yellow square on the left.
After 800 m we cross a paved path over a small swamp biotope on both sides.
From here, our hiking trail leads slightly uphill until it joins a forest road.
We turn left and after about 100 m we come to the "Hahnefurt crossing" with a small bench for a break before continuing slightly uphill.
After about 1 km we reach a small forest meadow on the left.
Here we turn left, walk slightly uphill and after 180 m we come to a hunting lodge.
From here a steep, 340 m long ascent awaits us to the plateau of the Carlshausturm, the highest point of the hike at 626 m above sea level.
Stamp lovers of the Harzer Wandernadel will find the stamping point no. 51 opposite the tower.
A weather shelter and a few benches invite you to take a break.
The viewing tower is a steel tower that can be walked on free of charge, with 150 steps up to the upper viewing platform at a height of approx. 30 m.
With the ascent of the tower, the efforts are rewarded with a fantastic view over the entire eastern Harz with the Brocken panorama and the view of the Josephskreuz and Kyffhäuser.
The first metal Carlshaus tower was built in 1901 by the Harzklub.
2nd stage: Return to Hasselfelde via the "Radeweghaus" = 7.2 km:
We follow the Harzklub signposts with the 'yellow dot' signpost to the tourist information office in Hasselfelde.
The way back leads us steeply downhill to the hunting lodge.
At the forest meadow, we turn right and hike back about 1.8 km to the "Hahnefurt crossing".
Here we follow the forest path to the right through an old mixed beech forest, past forest meadows and deer feeding areas to the "Radeweghaus" rest area on the B 81 (1.4 km).
After crossing the B 81 we turn left and after another 50 m we turn right onto a forest road.
In 850 m we come to a "forest path crossing in the forest village "Tänniche" (old beeches).
Here we turn left and we follow the 'yellow and red dot' waymarks until after 1.6 km to the weather protection hut at the gate of ski loipes.
On the last 1.6 km to the tourist information office in Hasselfelde, another view of the Brocken panorama awaits us on the left through an unusual Brocken telescope.
