An extensive marsh, a natural floodplain created by the La Crosse River, divides the city between north and south. The area is protected as an important wildlife habitat and watershed to the Mississippi River. Several biking and walking paths cross through the marshland, which is also used for canoeing, fishing, and trapping. On the southern end of the marsh lies Myrick Park. The park was named after the city's first European settler: Nathan Myrick. It has many recreational amenities as well as a nature center and environmental education department. Hunting and fishing are very popular all seasons of the year, and the Mississippi and other rivers, sloughs, creeks, lakes, the Upper Mississippi River Wildlife Refuge, and hilltops and valleys with public woodlands are available to sportsmen and families.
