Yankton sits along the wide Missouri River on the southern edge of South Dakota. It was once the capital of the whole Dakota Territory, giving it a proud history.
Play at Lake Yankton and the big Gavins Point Dam, walk across the historic Meridian Bridge, and watch for eagles and pelicans along the river.
The Missouri River and nearby Lewis and Clark Lake are perfect for boating, fishing and swimming, making Yankton a favorite summer spot.
This historic double-decker bridge is now a walking path across the river. Strolling over the water gives great views of the town and the wildlife below.
