Splash pads in Bismarck, North Dakota

Sertoma Park is Bismarck's Missouri River front yard — a destination playground, a splash pad, paved riverside trails, and the Dakota Zoo right next door for a paid afternoon add-on. The pad is gentle and toddler-sized, the playground is one of the better ones in the upper Plains. Free parking is plentiful. Short ND summer means peak season runs Memorial Day to Labor Day only — check city pool/pad hours before driving in from out of town. Parent gotcha: the river edge is unfenced and the current is strong — keep little ones above the seawall. Pack a picnic. Bismarck's signature free family afternoon.
