Badger Creek State Recreation Area is a popular fishing destination, with a large lake. There are no designated trails but there is wooded space to explore as well. Every year in mid-July, there is a large sunflower field that is popular for taking pictures (details below for the 2017 field location).
Windcrest Park is a small natural area with a pond for fishing and trails.
Lakeview Park has a lovely pond with trails all around, and a shady small playground.
