Checking In: Top Las Vegas spas

These Las Vegas spas are the perfect retreat when the sun rises and you’re regretting last night’s call for “one more round.”

The Spa at Four Seasons Hotel Las Vegas is small compared to some of the others on this list, but that actually works to its advantage. It’s a true oasis — never overwhelming and always relaxing, with an intimate design and a focus on results-oriented treatments. (No ridiculous, over-the-top facials here!) Perfect for the day after a Las Vegas night out, the Detoxify body wrap soothes aching muscles and draws out toxins with its secret ingredient — seaweed from the Brittany coast. Amenities include a large steam room and the Zen Lounge for serene relaxation.

Dramatic. That’s the Sahra Spa & Hammam at The Cosmopolitan. From walls made of red sandstone, to silver and twinkling ceilings that mimic a starry sky, this Las Vegas spa brings desert allure to the strip. For the quintessential Sahra Spa experience, book a treatment in the 1,200-square-foot hammam. Encompassing a heated motherstone slab, two whirlpools, steam rooms and stone loungers, the hammam can be used privately or with up to three of your closest friends. The Red Flower Hammam Experience is a favorite, with a lemon blossom scrub and clay wrap of cardamom.

Qua Baths and Spa at Caesars Palace is all about the natural healing power of water. The “Roman Baths,” or wet facilities, have three pools varying in temperature and there’s a Laconium Room (hot room) and Arctic Room with fake snowfall. Qua Baths and Spa promotes “social spa-ing,” which means it’s a great option for a chatty girlfriend getaway, but can be kind of loud if you’re looking for a true retreat. The Optimum Hydration facial blasts signs of stress with a Vitamin C peel and plant stem cells.

At 80,000 square feet, The Spa at ARIA is the largest on the Las Vegas strip. Sixty-two treatment rooms are accompanied by two truly innovative relaxation areas — one with heated black mineral stone beds, and another with glowing salt block walls, featuring lounge chairs that vibrate to music. Why salt? Apparently it has respiratory benefits! The Asian Bathhouse Ritual starts with a full-body exfoliation under a Vichy shower and includes a refreshing yogurt moisturizer, facial massage, and fresh cucumber face and neck mask.

Focusing on holistic health and natural ingredients, Vdara Hotel & Spa is all about organic freshness. Like the Four Seasons, this spa is prized for its smaller layout (by Vegas standards!) and personal touches. Treatments celebrate the purity of natural ingredients, like the Citrus Sorbet Body Polish or Lavender Soothing Massage. At the Vdara Pool & Lounge, you can book a spa cabana for special poolside treatments that use the Akhassa line from Thailand, which has hints of lemongrass and hibiscus.
