Spa Anjali at the Westin Riverfront

Spa Anjali sits inside the Westin Riverfront Resort & Spa in Avon, a short drive from Vail, and functions as both a hotel spa and a standalone wellness stop for day visitors. The facility runs 14 treatment rooms alongside a full-service salon, and guests who book a treatment or buy a day pass get access to the outdoor saline lap pool, three infinity hot tubs, and the attached Athletic Club.

The Athletic Club adds daily yoga, Pilates and cycling classes at no extra charge for spa guests, which makes this more of a half-day base than a quick massage stop. Hotel guests get 24-hour key access to the Athletic Club separately. The spa, pool deck and fitness areas are kept free of cell phones, pets and smoking, so plan on leaving devices behind once you're inside.

Spa Anjali has picked up some recognition over the years, including a readers' nod from Condé Nast Traveler as one of the world's top spas and a green-spa mention from Organic Spa Magazine, though neither changes the day-to-day experience: it's a well-equipped mountain resort spa built around treatments, water features and fitness classes rather than a niche bathhouse concept.

Hours shift across the week, running later on Fridays through Sundays (9am–7pm) and shorter midweek (10am–6pm). Given the 14-room count and resort setting, booking ahead is worth doing, especially around ski season or summer weekends when both hotel guests and day-pass visitors are drawing on the same schedule.
