Resort spas are a big business in the Valley of the Sun. The top-tier ones have their own hair and nail salons, men’s and women’s locker rooms, daily yoga and fitness classes, whirlpools, and the like. You start with massages and wraps and quickly ramp up to hot-stone therapies, hydrofacials, body treatments, and more. In other words, all the pampering and indulgence you could want.

Most resorts open their spas to the public, and for the cost of a body treatment or massage, you can spend the day doing yoga or lounging in the sauna or by the (often luxurious) pools. Rates plummet in the summer, but they’re sometimes higher on Fridays, Saturdays, and Sundays. Most of the top spas add on a 20% service charge for tips.

Well & Being Spa, at the Fairmont Scottsdale Princess, is the current champion in the resort spa arms race. It’s about as beautiful a place as you can imagine, more than 44,000 square feet, recently rebuilt into an experience that combines palatial surroundings with alluring tranquility. Over three floors, with a pool on the roof, the spa has everything from fitness classes to all the massages and treatments you could want. It’s a place worth spending the day at; there’s a towering waterfall bath in the grotto, and a secret garden reached via a path down from the pool. Wellness coaches are on hand for consultations. Because this is one of the largest spas in the Valley, you stand a better chance of getting last-minute reservations. Most 60-minute treatments cost $169 to $189. There are also several options for couples.

Sitting right at the foot of Mummy Mountain in Scottsdale, the Spa at Camelback Inn (; tel. 800/922-2635 or 480/596-7040) has long been one of the Valley’s premier spas.

For the cost of a single 1-hour treatment—between $130 and $175—you can use all the facilities, which include a fitness center and a lushly landscaped spa-only pool. There’s a healthy and friendly cafe, too. Among the treatments available are the Bindi Herbal Body Treatment, which will leave your skin feeling like silk, and the Sonoran Rose facial, perfect for making sure you come back from vacation looking like you were actually on one. Also everything from hair and nails to waxing. Packages run from $190 to $360.

One of the Valley’s most elegant spas, the Phoenician Spa (; tel. 480/423-2452) sits at the foot of the vast hill at Scottsdale’s Phoenician resort in a new extravagant building that holds the resort’s multi-tiered pools. Massages start at $165; leave time to choose and mix the essential oils you’d like to use beforehand. But that’s just the start of a kaleidoscope of treatments, classes, and other things on tap here, from daily yoga classes to a gemstone healing facial to a Kalahari hydration wrap to a session with an astrologer. Prices top out at $600.

The Spa Biltmore at the Arizona Biltmore, 2400 E. Missouri Ave., is as luscious as its resort surroundings. The spa menu includes a variety of massages, body scrubs, facials, and specialties like the Organic Super Fruit Hydration Wrap or a Volcanic Clay body scrub.

At Joya Spa, 4949 E. Lincoln Dr., Paradise Valley (; tel. 480/627-3020), in the Omni Scottsdale Resort & Spa at Montelucia, you’ll find the most romantic, and perhaps the largest, spa in the Valley. The spa’s signature treatment is the hammam ritual ($59), which involves relaxing in a warming room, then a scrub followed by an herbal steam bath, whirlpool, sauna, and cold deluge. Things get a little more elaborate with the Orroccan Orange Blossom Ritual, which includes a sugar rub, a Rhassoul clay mask, and a foot treatment; that’s about $250. Most 50-minute massages run $145 to $165, and there are various packages that let you choose two or three treatments, which have a top price of $430.

Spa Avania (; tel. 480/444-1234), at the Hyatt Regency Scottsdale Resort & Spa at Gainey Ranch, takes its name from the Greek work for “tranquil.” It’s an appropriately sprawling place for this sprawling resort, with nearly a dozen treatment rooms, a mineral pool, a lotus pond, and more.
