Bluemont Playground

The railroad-themed play train is honestly what makes this place — kids lose their minds for it, and it’s a nice change from the generic plastic equipment you see everywhere else. Bluemont sits right up against the woods, so even on hot summer days the shade trees keep things bearable, which Arlington parents will tell you is a big deal. The sandbox is generous-sized, the water feature keeps the little ones entertained longer than you’d expect, and there’s enough open grass for older kids to actually run around. Restrooms, picnic tables, and solid parking make it the kind of spot you can actually stay at for a few hours without scrambling.
