2026 Hot Springs in Illinois

We’ve cataloged 1 hot springs in Illinois, from 0 free & primitive pools to 1 resort experiences across the Midwest & Plains.

Illinois's hot springs scene is essentially one historic destination: Original Springs Hotel & Mineral Spa in Okawville, a 19th-century mineral-water resort that has been welcoming guests since 1867. The hotel taps cool mineral springs (not geothermally heated) and pipes the water into private soaking tubs and a small spa. It's a heritage soaking experience rather than the outdoor-pool format common in the Rockies. Year-round access by reservation; rooms and bath packages run $100–$200. Best for travelers seeking historic mineral-bath therapy rather than open-air hot pools.

Winter can freeze surface pools—target shoulder seasons or indoor bathhouses.
