Joplin now has its own water park. The Swimmin Hole is a privately owned and operated water park just east of town off 32nd street. They are not a huge place, but it is a lot of fun for those who go. They have cliff dives, lazy river and a lot of play area for the kids. It is a great place to go to cool off in the hot summer months. Price is kind of expensive though so you may want to get a pass if you plan on going a lot.
