Explore Baltimore/Washington

You may find yourself humming “The Star-Spangled Banner” while deplaning in Baltimore—after all, landmarked bastion Fort McHenry is where Francis Scott Key was originally inspired to pen the original poem. To catch some inspiration for yourself, take the water taxi from the Inner Harbor and take a look around. Monuments abound in Baltimore. John Quincy Adams was the first to call it Monument City, thanks to it being home to some of the earliest war monuments in the U.S. Wherever you wander, you’re sure to stumble upon something. Opportunities for learning and enrichment don’t stop at monuments, of course; Baltimore is home to dozens of museums, with something for every interest from pop culture to railroads.

Hope you’re hungry, and that you’re a fan of seafood. A trip to Baltimore is only made better by indulging in fresh Maryland blue crabs and other fresh, local favorites. Looking for something more refined? Harbor East features fine dining options to rival any foodie’s favorite. Want something more low key? Pick yourself up a chicken box and indulge in this local favorite on the go.
