Though Vegas is known for its party scene, head west towards Summerlin and Red Rock Canyon and you'll find a more laidback feel. Not only is Red Rock Casino Resort & Spa much smaller than the mammoth properties on the Strip, it's also home to the high-end Red Rock Spa. Treatments ideal for relaxation include the Himalayan Salt Stone Massage, where instead of hot stones, the skin is massaged using Himalayan crystal salt stones (50 minutes from $180, 80 minutes from $245).

The contrast between this zen-like spa and the hectic pace just outside its door is reason enough to book an appointment. Every treatment is created with balance in mind and inspired by nature, such as the Elemental Well-Being treatment and massage, which begins with a soak in a Japanese ofuro tub (75 minutes for $285, 105 minutes for $365). Also at the spa is a lantern-lit pool under a 250-year-old farmhouse reconstructed on site.
