Of course no true water park is complete without the requisite wave pool, and Seven Peaks doesn't disappoint with its Duneland Bay. The big of heart but small of stature will find plenty to do in the shallow waters of Sandbar Bay and Sandcastle Sliders -- fun interactive "spraygrounds" designed specifically with kids in mind. There are also various dry activities in which park goers may partake, including beach volley ball on courts of soft white sand, an indoor playland, and an arcade.
Note that the park was originally known as Splash Down Dunes before it reopened as Seven Peaks in 2013.
