Lewis and Clark spent the late-summer and early fall of 1804 exploring present-day South Dakota. Their return trip, in 1806, also led them back through the area. The captains' journal entries for this region described lush vegetation and wildlife, not to mention unusual sights like barking squirrels, burning bluffs and immense herds of buffalo. Walk where Lewis and Clark walked, see what they saw and feel what they felt as the sometimes wild and isolated trail is revealed. Now, 200 years later, you too, can experience the same rugged adventure along South Dakota's Lewis and Clark Trail.
