MUSEUM DISTRICT & FAIRMOUNT PARK. Touted as the largest city park in the world, Fairmount attracts more visitors each year than all of Philly's other attractions combined. Virtually every outdoor activity you can imagine is enjoyed here, from soccer and baseball to ultimate Frisbee and fishing. There's also a golf course, several playgrounds, a public pool, and bike paths. Attractions within the park include the zoo, museums, and many restored Colonial homes.

OLD CITY. Running along Philly's waterfront, Penn's Landing is the site of numerous events all year long, including cultural festivals, concerts (many of them free!), children's programs, and a host of other fun stuff. Attractions in the area include an international sculpture garden, Independence Seaport Museum, ships to tour, and an ice rink. A ferry links Philadelphia with Camden, where you can visit the New Jersey State Aquarium, Tweeter Center Amphitheater, and the South Jersey Performing Arts Center.

CENTER CITY. This site is considered to be one of the prettiest of all the squares in Philadelphia. Local residents come here to relax and forget about the hustle and bustle of the city. Visit the Curtis Institute of Music and the Rosenbach Museum and Library while at the square.
