The Spa at the Four Seasons Westlake Village, Westlake Village

Voted one of the top US spas by Condé Nast Traveler, The Spa at the Four Seasons Westlake Village overflows with opulence. The spa's lush gardens feature an authentic Chinese pagoda, an adults-only serenity pool, and 10 cabanas, as well as an ample supply of frozen fruit and sunscreen. The grandeur continues inside the 41,000-square-foot facility, an airy, tranquil space housing 28 treatment rooms where aestheticians offer 30 skincare treatments and massage therapists perform 12 types of massages. Read on to learn about some of the most luxurious treatments taking place inside:

• La Alternativa: This facial treatment employs Natura Bissé's Inhibit skincare line to noninvasively reduce expression lines and wrinkles, as well as prevent future ones.

• California Dream: A favorite of theFashionSpot, this body treatment begins by sloughing off dead skin cells with a combination of sugarcane extract, shea butter, and noni seed and safflower oils. A peppermint clay body mask then works to remove toxins and other impurities before an application of body butter caps everything off on a nourishing note.

• Somadome meditation: The Spa at the Four Seasons Westlake Village is among a handful of places in the country that features this cocoon-like meditation pod. The Somadome's 20-minute sessions may help to relieve stress and improve vitality thanks to a blend of color therapy, meditation, and energy healing.
