A comprehensive guide to Louisiana Plantations along the River Road. We recently visited 12 Louisiana plantations along Louisiana's River Road between Baton Rouge and New Orleans. Louisiana's River Road parallels the east and west banks of the Mississippi River for about 70 miles (about 100 miles of actual road) through the Louisiana parishes of St. Charles, St. John, and St. James. Over a dozen of the plantation homes are open to the public for tours, and all are different so it can be difficult to decide which to visit. Here is our guide to the Louisiana plantations along the River Road, complete with a FAQ section, a short guide to each of the 12 visited plantations, and our own impressions of each!
