Splash pads in Vienna, Virginia

Nottoway Park is the NoVA family secret — a Fairfax County park with a free spray ground, a huge destination playground, walking trails, and even a historic barn. Free parking, restrooms at the rec building. Best on weekday mornings before camp groups arrive. Operates Memorial Day through Labor Day. NoVA humidity in July is brutal but the park's mature tree canopy keeps things bearable. Pair with a picnic at the pavilions and a walk on the trail. The Vienna parent network considers this one of the best free family parks in the county — quieter than Burke Lake, more family-scaled than Lake Fairfax. A genuine NoVA gem.
