Towing and pushing their keelboat up the shallow, winding Missouri River in 1804, Lewis and Clark's band of explorers emerged from woodlands into the jaw-dropping vastness of the Great Plains of South Dakota. Today, modern dams have largely tamed the river on its north-south run through the state's heart to a dogleg near the Nebraska border. Even so, many spots along the broad Missouri valley still evoke the endless, rolling sea of grass the explorers found. Drive the Native American Scenic Byway to get a sense for the prairie, and stop in at the towns and small cities along the route.
The four huge, serpentine reservoirs formed along the river—Oahe, Lewis and Clark, Francis Case, and Sharpe—have an appeal all their own, with campgrounds, marinas and parks dotting thousands of miles of shore. South Dakota's Park's and Recreation Department maintains many areas around the lakes.
