At Avalanche Ranch near Carbondale, about an hour from Aspen, we tiptoe away from our bunk — Dog Cabin — long before dawn. The rocky road impedes our progress as we stumble along; our path is lit by preternaturally bright stars and a fulgent moon. Somewhere in the velvety early morning milieu a cow moos, just before something rises menacingly from behind a pine tree. We shriek, terrified — after all, we are deep in the wilds of western Colorado mountain country. “It’s just the llama,” says my husband, as the beast looks on, offended at our reaction. As we scurry along, giggling quietly, our bathrobes gaping to reveal swimsuits, we hush one another. We don’t want to wake any other guests because we’re determined to be the first at the retreat’s natural hot springs pools to watch the sun rise and float in sulfur-y, mineral-imbued depths. It’s the routine we’ve followed for several days at this paradisiacal retreat, one of multiple stops on our Colorado Historic Hot Springs road trip, an 800-mile loop that guides drivers, wellness seekers, and soakers to 23 unique, natural hot springs clustered among eight peerless locations. 

The Colorado Historic Hot Springs Loop

Nearly 100 known hot springs pepper western Colorado’s mountainous terrain. The 23 mapped out by Colorado Historic Hot Springs are touted as among the most famous. They range from the biggest hot springs pool in the world to the deepest geothermal hot springs on earth to rustic-chic spots with cabins (like Avalanche Ranch) to swankier lodges suffused with old-school national park charm. To drive and enjoy the gamut can take a couple of weeks if you allow yourself a leisurely pace that includes a host of submersions — and languid nights in characteristic inns, fancy hotels, yurts, and log-walled huts. Along the way, you’ll take in historic sites, national parks, ancient monuments, ghost towns, scenic overlooks, and the occasional invigorating hikes through the woods. Enjoy vapor caves, water slides, funky tubs wedged mountainside, and romantic nooks and crannies. For a long weekend, simply choose just a portion of the loop — even one property amongst the 23. All that’s left after that is to soak up the wellness.

The Full Meal Deal

Embody your best Jack Kerouac road warrior spirit for this balneotherapy-themed road trip, rife with hair pin turns and unforgettable views. Begin in Denver after an easy arrival to Denver International Airport (DIA). Head toward Chaffee County, where vibrant hamlets like Salida, Nathrop, and Buena Vista await about three hours away. Onward in a southerly direction, steer toward Saguache County, Pagosa Springs, Durango, and Ouray, dawdling as you get drenched.  Then, wend in a westerly direction to historic Glenwood Springs, home to a world-famous hot springs pool.

Next up: artsy Carbondale has a variety of  hotspots (like Avalanche Ranch) on its verges. Complete the watery loop in Steamboat Springs, a beloved ski town, which has both a pool playground downtown, as well and a time honored  hideaway a few miles outside city limits. Want to do the loop the other way around? That’s up you!

Why Soak and what is Balneotherapy?

Getting waterlogged as a means to better health is instinctive to humans. Even animals feel the urge to dunk themselves in geothermal waters for well-being (think: snow monkeys in Japan).  Called balneotherapy, the practice of bathing in geothermal pools goes back to ancient times. It continues to be part of traditional medical practices around the world, and purportedly  promotes relaxation, improves skin conditions, helps with aches and pains, and boosts the immune system. Just being beside or around water can lower blood pressure, bring solace, and induce grounding. Water sourced from the earth’s core comprises curative doses of minerals such as magnesium, calcium, potassium, fluoride, lithium, silica, phosphate — even  arsenic. On Colorado’s Hot Springs Loop, you’ll find mineral-rich waters aplenty. You’ll  marinate in elegant terraced pools, vintage bathtubs, rustic barrels, and muddy river tributaries. Will it be stinky? Maybe. Will you ruin a suit or two? Absolutely. Is it worth it? A hundred times yes.
