Splash pads in Alexandria, Virginia

Cameron Run Regional Park is NoVA's go-to mid-summer water destination — splash play, big slides, a wave pool, and a mini-golf course on one campus. NOVA Parks runs it; admission is paid (around $14–18) but the whole complex is included. Free parking is generous; restrooms and locker rooms are full-service. Best on weekday mornings before camp groups arrive. Operates Memorial Day through Labor Day, weather permitting. NoVA humidity in July is brutal but you're in the water all day. Bring a picnic — the on-site food is basic. The single best paid water-park value in the DMV for families with kids ages 4–12.
