5. Browse the free books at The Book Thing

The Book Thing is home to thousands of free books, but unlike a library you don’t have to bring them back. The Book Thing of Baltimore is located at 3001 Vineyard Lane Baltimore, MD 21218 and is open every Saturday and Sunday from 9 a.m. to 6 p.m. For more information, read my detailed post here.

6. Pack a picnic for Federal Hill park

I guess this one’s not totally free, since you would have to buy food for the picnic... but the views are 100 percent free, and arguably the best in Baltimore. If you’ve never taken the time to walk to the top of Federal Hill and look out at Baltimore, you’re missing out. It’s the ideal spot for a spring picnic and a walk in the park. After you take in the views up top, take a few minutes to walk through the Sculpture Garden at the American Visionary Arts museum, which is also free!

7. Check out the incredible works of art at The Walters Art Museum

General admission to the Walters Art Museum is… you guessed it… FREE! Open Wednesday through Sunday from 10 a.m. – 5 p.m., this museum features art from the third millennium B.C. to the early 20th century. The museum is located in the heart of Mount Vernon and features artworks from around the world. I'm not an art expert, but I found the art here to be “classic” as opposed to the more contemporary pieces at the BMA. So don’t feel like you have to choose one museum or the other, they’re very different.
