Manomin County Park is part of the Anoka County Park system, though it has not always been. Anoka County acquired them in 1967, and it is 15 acres at the confluence of Mississippi River and Rice Creek.
If you are an outdoor enthusiast, then this is the park for you. You can walk along the creek and watch fishermen catch sunnies, crappies, northern pikes, and more.
There is also connection to the Mississippi River Regional Trail, which is several miles long, so it's a lovely hike with so much to see along the way.
