Devil's Thumb Ranch Resort & Spa

Devil's Thumb Ranch Resort & Spa sits on 6,500 acres of Rocky Mountain wilderness near Tabernash, Colorado, about two hours from Denver. It's a resort spa built into a working ranch property, meaning access runs through the lodge itself: there's no day-pass option, and the spa and its amenities are reserved for overnight guests.

The signature water feature is Rachel's Pool, an outdoor pool and hot tub heated with geothermal energy and kept open year-round, whether that means cooling off in summer or soaking after a day in the snow. Couples treatments are offered, fitting a property that leans toward multi-night stays rather than quick drop-in visits.

Beyond the spa, the ranch runs on its own rhythm. Heck's Tavern serves casual ranch fare and craft beer to lodging guests, Hallowed Grounds Café handles coffee and pastries, and the Ranch House Restaurant, set in a 1930s homestead building, serves modern Western cuisine including Wagyu beef from the ranch's own herd and picked up a Wine Spectator Best of Award of Excellence in 2023. Outside the spa and dining rooms, the grounds are set up for cross-country skiing, snowshoeing, mountain biking, fishing, and archery, so a spa visit here tends to be one piece of a longer outdoor-focused stay rather than the whole point of the trip.

The property falls into the upscale price tier. Posted hours data for the resort is inconsistent, so it's worth calling ahead or checking the website directly to confirm spa scheduling, treatment availability, and any current booking requirements before planning a visit.
