Philadelphia

 A series of projects has transformed Philadelphia into a hive of outdoor urban activity. Dilworth Park, formerly a hideous slab of concrete adjoining City Hall, reopened this past autumn as a green, pedestrian-friendly public space with a winter ice-skating rink (and a cafe by the indefatigable chef Jose Garces). Public art installations, mini "parklets" and open-air beer gardens have become common sights. The Delaware River waterfront was reworked for summer 2014 with the Spruce Street Harbor Park (complete with hammocks, lanterns and floating bar) becoming a new fixture, following the renovation of the Race Street Pier, completed in 2011, and offers free yoga classes on a bi-level strip of high-design decking and grass. The city’s other river, the Schuylkill, has its own new boardwalk. To top it off, this spring, Philadelphia will get its first bike share program, making this mostly flat city even more friendly for those on two wheels. NELL MCSHANE WULFHART
