Philadelphia may be a bustling urban center, but the Philadelphia spa scene offers an escape from it all. At the David J. Witchell—which Philadelphia magazine named one of the best spas in Philadelphia—clients descend a flight of stairs to the grotto-level spa, where they trade their cell phones and laptops for a cozy robe and slippers. The spa calls to mind a mountaintop chalet, all knotty wood and rugged stone. From its own luxe location within the Rittenhouse Hotel, the Rittenhouse Spa & Club offers head-to-toe pampering. Everything from scalp massages to exfoliating honey scrubs make it easy to wind down from an adrenaline-packed adventure in the city outside.
