Following an $8 million facelift, the Spa at Camelback Inn has swapped its old Southwest-style décor for sophisticated chocolate brown woods, flagstone walls and expansive windows to create an inviting, placid retreat. If the gas fireplace in the main relaxation room doesn’t soothe your spirit, head outside to the solarium and let the sound of rippling water from a flowing fountain do the trick. Relax in your own private casita, while you choose from the menu of massages, facials and body treatments—many of which draw from Native American techniques and indigenous ingredients.
