Suson Park is a little piece of wonderful seated right between the South St. Louis area and Jefferson County. On a pretty day, you'll see lots of people in their lawn chairs fishing in one of several fishing lakes. LOVE that! The playground is pretty big with even a place for simulated rock climbing for the kiddos. The grounds are kept impeccably clean. The best part though is the petting zoo or the barn where the little ones can walk through and pet the animals. There is NO fee for this, there's only a place where if you WANT to, you can leave a donation and all the $ is spent on the animals.
There are pavilions to be reserved for parties and large picnic areas that you can use for free (first come first serve) for parties. This is just a great place to come and relax. Still a safe place for the kids :-)
