Ft Ancient is located on the Little Miami River on highway State Route 350, off of Interstate 71. Not far from Lebanon, Morrow and South Lebanon in Warren county. It is now a popular spot for canoe trips on the river. It is one of the Ohio sites of the prehistoric Indian Mounds and the Native America Museum located here is worth checking out. There are hiking trails too. "Life is what happens while your making other plans"
