Fort Mandan is a brilliant full-scale reconstruction of the fort at which the Lewis and Clark party spent the winter of 1804-05 (with the invaluable support of the local Mandan-Hidatsa Indians) and where, on February 11, 1805, Sacagawea gave birth to her son Jean-Baptiste. Each room is kitted out as it would have been over 200 years ago and well-informed guides are on hand to provides the insights into the party's time there.
If you go:
Take a stroll by the majestic Missouri River, just a stone's throw from the gates of the fort.
