North Shore Beach Club, Philadelphia

A luxe oasis in the middle of the city, North Shore Beach Club invites members to kick back at a crystalline rooftop pool in the Northern Liberties neighborhood. The semiprivate club's 1,500-square-foot pool is flanked by plush cabanas and Balinese lounge chairs, which members never need to leave thanks to poolside food and beverage service. Aside from the pool, the club offers a variety of other amenities including an upper-level sun deck, a fire-pit lounge, an outdoor bar and restaurant, and live music.
