Pioneer Tunnel (Pioniertunnel)

Highlight • Structure

An approximately ten meter long rock breakthrough on the pioneer path. There's no way around it. In the truest sense of the word "We have to get through this". :-)

Glasebach Adit (HWN 175)

Highlight • Historical Site

Beautiful stamping point for the Harz hiking pin with a rest area. We particularly like it here in summer, as the area is completely in the cool shade.

Cool thing, and I forgot the lamp, screams for a second visit.
The mausoleum, the tunnels, and the castle make Hakerode a worthwhile starting point.

Valley of the Holy Reiser

Highlight • Gorge

Great rock outcrop, everything worth knowing is on an information board, it's just a shame it's not very well maintained and a place to sit would be nice, it's a great place.🫶

The small stone cave is located between Alexisbad and Klostermühle, right on the Selke. Nice photo opportunity

The Pioneer Tunnel is a stop on the Selketalstieg between Alexisbad and Mägdesprung and is located on the east side of the picturesque Selke Valley. This artificial, around 10 meters long and relatively low passage was driven through the rock in May 1900 within a few days. The hiking trail leads through here. There is no alternative route over or around the rock, so if you don't want to turn back you have to squeeze through the narrow tunnel. On the south side of the tunnel you have a beautiful view of the Selke Valley and the surrounding mountains. Source: https://www.harzlife.de/bilder/pioniertunnel.html

Last weekend (06/11/23) the door to the secret passage was ajar, but not locked!

About 30 years ago, I explored this tunnel with the shaft with a friend. We discovered the upper end of the shaft. It doesn't end inside the ruins, but at the edge of the ruins. We were able to throw a stone in there. The upper end was so big that it was impossible to break through. I think the upper end was closed for safety reasons! I would still be able to find out where the end is today.

20 meters to the door you can still get into the tunnel, then unfortunately closed, too bad 🥺
