Splash pads in Arlington, Virginia

Long Bridge Park is Arlington's modern crown jewel — a multi-zone spray plaza next to the new aquatics center, with skyline views of DC across the Potomac. Splash play is free; pool admission is separate (around $8 county residents). Free parking; restrooms inside the aquatics center. Best on weekday mornings before camp groups arrive. Operates Memorial Day through Labor Day. NoVA humidity is heavy from June through September; afternoon thunderstorms close things briefly. Pair with a walk along the Mt. Vernon Trail or dinner in Crystal City after. The most architecturally striking splash plaza in the DMV — and free.
