Swimming pool and waterplay
Folf (frisbee golf), playground and ampitheater just outside the aquatic center at Rotary Park. A great place to picnic before or after some swim time.
We visited the Aquatic Center as a field trip during summer school. It was nice and the kids had fun but not sure I would want to go there when there were more people as I think it would get a little crowded. It was nice that they had lots of areas for the kids to play that were not all deep water. Also they did have a good number of life guards on duty. My daughter did not know how to swim at the time and I felt that she would be watched and safe
This outdoor and indoor water park may not be the most grandiose, but for Northeast Missouri it is one of the best outdoor summer activity locations. The outdoor park has kiddie areas as well as a larger slide and diving board. The indoor pool is great for lap swimming or free play any time of the year. All in all a fun place to play in this small town.
