Mud Island is a fun park located on an island lying in the Mississippi River. It is best known for its scaled replica of the Mississippi River, called the Riverwalk. If you park on the residential part of the island, you can walk to the Riverwalk and enjoy it for free. Parking for a fee is available off of Front Street, and you can ride the monorail to the Island for a fee or walk across for free.
