Wyman Park Dell, Johns Hopkins/Homewood
The 16-acre, bowl-like dell shields visitors from traffic on Charles and 29th streets. The shady lawns and slopes are especially helpful when seeking protection from the full heat of a Baltimore summer.

Patterson Park, Upper Fells Point/Butchers Hill/Canton
Pick your picturesque position: by the boat lake, perched near the pagoda, in front of the marble fountain, or down by the dog parks. Grab grub from any of the nearby eateries. We recommend a crab pie from Matthew’s Pizza.

Lake Kittamaqundi, Columbia
Shake off suburban office park stupor with a jaunt around this 27-acre man-made lake. Pop over to the nearby Whole Foods for a grab-and-go meal and you’ll be back at your desk with time to spare.

Federal Hill Park, Federal Hill
Gaze upon the hustle and bustle of downtown at this grassy rise overlooking the Inner Harbor. Benches, monuments, and a large playground make it fun for the whole family.

Benjamin Banneker Historical Park & Museum, Catonsville
This 142-acre site honors the life of Benjamin Banneker, often called the first African-American man of science. The park offers good walking trails and picnic areas, but do make time for the exhibits, too. Snacks from either Atwater’s or The Breadery will complete the experience.

Fort McHenry, Locust Point
The star-shaped fort played a “key” role in American history when Francis Scott Key watched its bombardment during the War of 1812 and wrote what would become the lyrics to our national anthem. There’s a $10 entrance fee to the historic area, but walking the perimeter along the water is free.

Hampton National Historic Site, Towson
There’s plenty to absorb at this former estate that once belonged to the prominent Ridgely family, from the beauty of the stately, cream-colored Georgian mansion to the sobering exhibits on slavery and indentured servitude.
