Mystic Hot Springs was previously known as Monroe Hot Springs and Cooper Hot Springs, and the bathing site itself has been used for over a century. The current operation began in 1996 when Mike Ginsburg, a musician (and committed Grateful Dead fan) traveling home from a concert in his tour bus, stopped at the property, fell in love with it, and bought it. The hippie aesthetic, the live-music programming, and the deliberately rustic atmosphere all date to that 1996 acquisition.
What makes Mystic visually unique is the geology. Geothermal mineral water emerges from the source at 168 F (high enough to scald) and flows through a channel and out across a small hillside, depositing calcium carbonate as it cools. Over thousands of years the mineral deposition has built rust-colored travertine mounds, similar in geology to the travertine of Yellowstone's Mammoth Hot Springs or California's Travertine Hot Springs. The previous owners placed cast-iron claw-foot bathtubs directly in the mound, and the same mineral deposition that built the mounds is now slowly engulfing the tubs. Photographs of soakers in tubs half-encased in mineral deposits are the signature Mystic image.
Eight bathtubs perch in the mounds at varying temperatures, all cooler than the source because the water has traveled and cooled. Below the mounds, two concrete soaking pools take the rest of the flow and run at 92 to 102 F. The soaking experience is fundamentally outdoor and weather-exposed: there is no covered bathhouse, the tubs are open to the sky, and visitors should plan around weather for winter and shoulder-season visits.
The on-site concert venue is the second product. Three stages including an acoustic stage that allows guests to soak while listening to live music. A summer music festival runs in July. Live concerts continue year-round; the operator's event calendar is the source of truth for what's on during any given visit. Overnight lodging includes cabins, vintage school buses converted to rooms, tipis, and yurts, all in keeping with the rustic-hippie aesthetic. The on-site cafe handles food.
