The options are endless in entertainment-rich Las Vegas and that includes invigorating spas and salons. You'll find plenty throughout Sin City but discerning wellness-minded travelers can narrow the list down to a select few. Here are five guaranteed to bring you much-needed relaxation and serenity.

MGM Resorts International's ARIA Resort & Casino is home to the largest Forbes Five-Star spa and salon in the country and has got everything you need to rejuvenate your skin, muscles and mind, whether you're breathing in salt-infused air in the Shio Salt Room or parting ways with your tension on a heated-stone Ganbanyoku bed. Guests can purchase a daily facility pass for as little as $50 Monday through Thursday. Summer specials available include the Lavender Bliss Massage and Diamond Chakra Radiance.

Another one-of-a-kind spa on The Strip, Bellagio Spa & Salon is the only in the region to offer guests rituals from global beauty atelier Cinq Mondes. Spa facilities here include a steam room, sauna, cold plunge pool and three Whirlpools. Not sure where to begin? Address your stress, toxins and inflammation while restoring all of your vital systems with an 80-minute recovery aromatherapy massage.

Treat yourself at The Spa at Park MGM, where you can schedule relaxing facials and body massages as well as skin treatments and waxing. Seasonal spa treatments offered here include a 50-minute coconut brown sugar scrub while those seeking holistic healing can take part in Park MGM's weekly yoga series.

Guests staying at the Mandalay Bay will be tempted to purchase a day pass for Spa Mandalay, which offers a whopping 30,000 square feet of pure relaxation. Hotel guests can snag a day pass for as little as $30 and gain access to a slew of facilities, including the Redwood Sauna, a relaxation lounge, heated Whirlpools, the Eucalyptus Steam Room and exercise room. Make the most of the summer season with a coconut lime escape massage or coconut lime body scrub.

The dog-friendly Delano Las Vegas is a huge hit with pet lovers, of course, but also wins over guests with its BATHHOUSE Spa, which offers calming stream rooms and saunas in addition to a dozen treatment rooms and a fully equipped workout facility. Soothe those sore muscles with a relaxing soak in eucalyptus, lavender and peppermint essential oils or seek out an anti-aging and anti-inflammatory treatment such as the Moor Mud Bath.
