The National Park Service's unique contribution to the bicentennial—the Corps of Discovery II: 200 Years to the Future —is a traveling education center that will recreate the epic journey and be the unifying component for the Lewis and Clark Bicentennial observance.
If you are planning a trip for a group, you will frequently need a permit to float, camp or picnic in certain areas. Below are some of the agencies who oversee these areas.
