Follow the Lewis and Clark Trail across North Dakota.
Famed frontier explorers Meriwether Lewis and William Clark spent more time in present-day North Dakota than any other state on their epic two-year expedition. To retrace their steps, start in the state capital of Bismarck and follow the Missouri River north to the Lewis & Clark Interpretive Center in Washburn. Nearby you'll find both Fort Mandan, the winter home of the expedition from 1804–1805, and Knife River Indian Villages, where the explorers met their Shoshone guide, Sacagawea. Continue westward past the oil boom town of Williston to Fort Buford and the meeting of two of America's great rivers: the Missouri and Yellowstone. The Confluence Interpretive Center here tells of the explorers' onward journey. Visit in summer when the seasonal museums and parks are all open.
