The Ritz-Carlton Spa, Denver

The Ritz-Carlton Spa, Denver sits inside the hotel's Granite Tower building in the Ballpark District and has been operating since May 2008. It's an adults-only space — guests must be 18 or over — built around steam rooms, whirlpools, separate men's and women's relaxation lounges, and an adjoining fitness center with free weights, Pelotons, and treadmills.

The treatment menu runs through facials, massages, body scrubs and wraps, and couples massages, with men's-specific services also listed. The signature offering is a body ritual built around craft beer, aimed at tightening and hydrating skin — a nod to Denver's brewing culture. Couples treatments are available for those booking together.

Access doesn't require a hotel stay. A day pass runs $40 for in-house hotel guests and $75 for outside visitors, with the outside-guest pass including complimentary parking. Either pass comes with a glass of bubbles or wine and a 20% discount on retail products. The spa is not limited to overnight guests, so a day trip from elsewhere in Denver is straightforward to arrange.

Hours shift slightly through the week: open 9am to 5pm Sunday through Thursday, and 9am to 7pm on Friday and Saturday. English is the primary language spoken. Treatment reservations go through the spa directly by phone, and arriving 15 minutes early is standard practice here, since late arrivals cut into the scheduled service time rather than extending it. A 24-hour cancellation window applies before the full treatment charge becomes non-refundable.
