Leukerbad Therme

Leukerbad sits on Roman-era foundations, its hot springs known as far back as antiquity for their calcium-sulphate, gypsum-rich waters. Today 65 individual thermal springs, grouped into eight source areas, deliver around 3.9 million liters of water daily, emerging at up to 51°C before the roughly 2,800-meter descent that brings it down the mountain to the village. The water forms as it filters through Triassic gypsum deposits deep underground, picking up calcium and sulphate before rising to the surface, giving Leukerbad the richest concentration of thermal water anywhere in Europe. The village's public and hotel-operated thermal baths, including the Walliser Alpentherme on the historic Dorfplatz, draw directly on this network of springs, long valued for treating rheumatic and neurological conditions.
