Independence Blue Cross RiverRink Summerfest goes on between May ~ September! Check out the roller skating rink, carnival games, food & drink on the Delaware Riverfront!
Spruce st. Harbor Park is attached to Penn's Landing, but they have a nice beer garden with hammocks over the Delaware river!
The art museum is a classic! You too can line up to take a picture on the Rocky steps.
If you're into frisbee, check out this disc golf course in Fairmount Park! If you're not into frisbee, then tag along a friend who is into frisbee so you can go on a nice nature walk and meet some chipmunks! They are adorable!
Who doesn't love zoos?! You can feed the giraffes and roam with the peacocks.
Follow the trails to Devil's Pool. Bring a bathing suit and get ready to rope-swing into the creek!
FDR park is not only a nice park, it also hosts the Southeast Asian Market during the summer! https://www.fdrseamarket.com/
