For a small fee (youth= $5; adults=$7), you can visit the Miller Park Zoo! they have many animals from Red Pandas to Alligators! 🐊
If you want to go with a group activity, bowling can be the way to go! I (Emily) prefer this location, because you rent by the game, while the other locations are by the hour (I've been on a strike roll before and had the game stop due to the time limit... It's a sad sight).
