Four Seasons Hotel Westlake Village, California.

Set against the Santa Monica Mountains, this sprawling property functions more as a comprehensive health retreat than a standard suburban hotel. While the aesthetic leans into coastal California glam with stone accents and floor-to-ceiling mountain views, the real draw is the 40,000-square-foot spa—the largest in the brand’s portfolio. The on-site Center for Health & Wellbeing anchors the experience, offering everything from interactive culinary classes in a dedicated wellness kitchen to intensive fitness programming. Outside, 12 acres of manicured grounds feature a Chinese pagoda, an orchid greenhouse, and a waterfall-fed serenity pool. For a change of pace, the Prosperous Penny speakeasy provides an intimate cocktail setting, balancing the property's rigorous focus on vitality.
