Lewis and Clark State Park in Monona County, Iowa, covers 176 acres beside Blue Lake and serves as a popular destination for camping, picnicking, boating, swimming, and fishing. Its 95 electric campsites make it especially attractive to overnight visitors. The park also has a strong connection to the Lewis and Clark Expedition, which passed through this area in 1804 while traveling up the Missouri River. A full-size replica of a keelboat like the one used on that journey connects the park’s modern recreational role with the history of the expedition’s route through western Iowa.
