This section of the Lewis & Clark Bicycle Trail continues to follow the Missouri River and goes through Sioux City, Iowa, before entering South Dakota. Due to dams, the Missouri shifts from a river to a lake, three of them in fact: Lewis and Clark Lake, Lake Francis Case and Lake Sharpe. The terrain becomes more rolling; there will always be a descent/ascent when crossing the river. Two options are available to customize your route. The Whetstone Bay Option is 25.5 miles in length (including 14.5 on hard-packed dirt and gravel) that takes you closer to Missouri/Lake Francis Case. The second option is an alternate way into Pierre, the endpoint of this section. Major funding for the Lewis & Clark Bicycle Trail has been provided by REI. More information about this route is available here.
