Yampah Spa & Vapor Caves
“Doc Holliday showed up coughing in 1887. You lie on marble slabs in the dim. Nobody talks.”
Twenty steps below an 1893 spa building, 125-degree mineral water runs through channels in the floor of three rock chambers, filling them with 110-plus-degree steam — the only natural vapor caves in North America. The Utes called this place Yampah, "big medicine," and steamed here centuries before Doc Holliday showed up coughing in 1887. You lie on marble slabs in the dim, douse yourself at a cold spigot when you cannot take it anymore, and nobody talks. House rule.
The story
Long before an 1893 spa building was erected on the north bank of the Colorado River, the Ute people knew this subterranean fissure as Yampah, or "big medicine." They descended into the natural rock chambers to inhale hot mineral vapors for healing long before coughing gunfighter Doc Holliday rolled into Glenwood Springs in 1887 hoping the mountain steam would cure his tuberculosis.
What makes this cavern distinct—and the only natural vapor cave system in North America—is that you aren't sitting in a tub of hot water; you're breathing it. Deep below the floor, 125-degree geothermal water flows through narrow concrete channels carved into three dark rock chambers. The raw heat radiates off the stone, thick with sulfur and trace minerals, raising the ambient air temperature inside the caves to a dense, sweltering 110 degrees.
The subterranean layout remains refreshingly primitive. There are no halogen lights, no ambient music, and no hydrotherapy jets down here—just wet stone walls, smooth marble benches, and cold water spigots placed near the ground for when your core temperature creeps into discomfort.
What it's like
Leave your jewelry and phone locked in the dressing room upstairs; the mineral-thick steam corrodes metal and destroys delicate electronics in short order. You'll put on a swimsuit and descend roughly twenty stone steps into a humid stone corridor. Pick one of the three dim subterranean chambers, lay out on a slab of marble, and embrace the heat in total silence—talking is strictly forbidden by house rule. When ten minutes feels like an eternity, step over to a cold-water spigot to douse your face before retreating upstairs to recover in the solarium.
The move: Book a cave slot for two, alternate ten-minute steams on the marble benches with cold-spigot dunks, then recover side by side in the upstairs solarium.
📍 Before you go The spa sits at the east end of 6th Street on the north bank of the Colorado River, about 90 minutes from Grand Junction on I-70 through Glenwood Canyon, with parking out front. You enter through the lobby and descend roughly 20 steps through a stone corridor, so the caves are not wheelchair-accessible; swimsuits are required, the chambers are kept silent, and electronics and jewelry stay in your locker because the heat ruins them. Reserve a cave slot ahead rather than dropping in — a cave pass also comes bundled with any massage or treatment. Pair it with the Glenwood Hot Springs pool a few blocks west or the short, steep walk up to Doc Holliday's grave at Linwood Cemetery.

Good to know
Why do electronics and jewelry have to stay in the locker?
The 110-plus-degree steam is heavily mineralized with sulfur and other compounds that will tarnish metals and ruin electronic devices within minutes.
Are the vapor caves wheelchair accessible?
No. Accessing the caves requires descending approximately 20 stone steps down a narrow subterranean corridor.
What do I need to bring and wear?
Swimsuits are mandatory in the shared caves. Bring flip-flops or water shoes, and remember to reserve a time slot online in advance rather than walking in.
How far are the caves from Grand Junction?
They sit about 90 minutes east of Grand Junction via I-70, located at the east end of 6th Street in Glenwood Springs.
