The Kalmithaus, also called the Ludwigshafener Hut, near Maikammer in the Rhineland-Palatinate county of Südliche Weinstraße is a refuge hut in the Palatinate Forest run by the Ludwigshafen-Mannheim branch of the Palatinate Forest Club. It is located in the southern part of the Haardt mountains at the summit of its highest peak, the Kalmit , and is thus the highest hut in the Palatinate Forest. From its terrace there is often a stunning view of the Upper Rhine Plain as far as the foothills of the southern Odenwald and northern Black Forest. Immediately next to the hut is the observation tower on the Kalmit, which is out of bounds to the public, and houses a radio relay station, a weather station and a visibility survey station.
