Louisiana Purchase Historic State Park is a day park and National Historic Landmark which preserves the spot from which all land surveys of property acquired by the Louisiana Purchase were made. A granite monument marks the actual spot which was used for the land surveys and you can learn all about the importance of the Louisiana Purchase from wayside exhibits as you make your way along the elevated boardwalk over the head-water swamp. Besides learning about history, nature lovers will enjoy spotting a variety of animals, birds and endemic plants. As this is a day-use park camping is not allowed but restrooms are available.
