Mandarin Oriental This 27,000-square-foot, two-story retreat is easily the most luxurious spa in Sin City.

Each visit begins with a footbath, the shortest massage lasts 80 minutes, and the hammam isn’t merely a steam but a true Turkish indulgence, complete with an attended loofah scrub. Rates from $295; massage from $250.
Four Seasons This was the first resort in Vegas to get it right, and the intimacy of this oasis makes each guest feel like the center of the universe in an otherwise chaotic town.

Plus, there’s an on-site parfumerie, where guests can create a unique fragrance to meld with their body’s own chemistry. Rates from $290; massage from $230…
