Arizona Biltmore Spa

The spa pass works as a simple hot and cold loop: an aroma-infused steam room and a hot tub for heat, a cold plunge pool for the contrast, and the Sol Garden with an outdoor rain shower and chaise lounges for resting between rounds. There is no dry sauna listed with the pass.

The pass also covers the Catalina Pool, a relaxation lounge, the changing area and the fitness center, while the resort's Paradise and Saguaro pools need their own day pass. Guests must be 18 or older, and the pass is sold for weekday visits. A service fee is added when you check in.
