Actually, there is already a highlight here and you shouldn't create another one. But it is a good place to rest or as a shelter from the rain. The hut is nicer from the outside than from the inside.
The Naturfreundehaus is located on the edge of the Neuchâtel jungle in Zetel and offers conference and overnight accommodation for groups (prior reservation). Info: naturfreunde.de/haus/naturfreundehaus-zetel
