The park is located near the site of the former Harmonist and Owenite communal societies, which were early 19th-century utopian experiments.
The Wabash River serves as the park's western border, providing a natural habitat for diverse aquatic and riparian life.
The park contains significant stands of old-growth sycamore trees along the river's edge.
Many of the park trails are built over terrain once used by the early settlers for agricultural transport between the river and the town of New Harmony.
The Indiana state record for a sycamore tree is located within the general vicinity of the park's river bottom area.
