Trudge uphill to one of the city’s classic hotels, and you’ll be rewarded with a posh spot for top-notch pampering. The bi-level space offers 10 treatment rooms, an indoor pool, saunas and steam rooms, and a workout area—all of which are overseen by friendly, but unobtrusive staffers. Indulge in a High Skin Refiner Facial ($205), which helps smooth out wrinkles and lines, or the Ultimate Massage ($295)—a 110-minute customized blissfest in which you’re kneaded with aromatherapeutic oils and hot stones that’ll leave you so relaxed you may need a ride home. Or take some time to compose yourself first by ordering a light lunch (Nob Hill is one of the rare spas to offer more than cucumbers and water on its spa menu) while taking in the city views from the balcony patio.
