Rotherma is located in Neuenbürg, Baden-Württemberg, Germany, on the edge of the Black Forest. Its thermal water emerges at 38°C and feeds both an indoor and an outdoor pool.
Insider tip — Rotherma takes its name from the Roth valley in the Northern Black Forest, where thermal spring water is captured and delivered through a modern wellness facility with indoor and outdoor pool landscapes. The spa sits at the edge of the Black Forest National Park, and forest walking trails accessible directly from the premises make it easy to alternate bathing with hiking through old-growth fir and beech stands. Water temperatures are calibrated to promote extended stays, and the sauna section includes a panoramic Finnish sauna facing the forested hillside. The combination of forest air and warm mineral water draws guests seeking genuine recuperation rather than mere leisure.
