The spa at Omni Tucson National Resort is no average getaway. Encompassing 13,000 square feet of the four-star hotel, it offers services that range from the 25-minute express massage to the six-hour-long Indulgence Package, a true retreat that includes a Swedish massage, volcanic clay wrap, custom facial, and mani-pedi. As for amenities, every treatment grants access to a men's or women's relaxation room, a palatial oasis where clients lounge in the whirlpool and sauna between dips in the cold plunge. A plush bathrobe and slippers ensure complete comfort, and a day pass to the resort's Sweetwater pool completes the escape, allowing clients to bask in total relaxation after their trip to the spa.
