Welcome Center boatLocated on Sioux City's riverfront, the Sergeant Floyd River Museum and Welcome Center is adjacent to the Chris Larsen Park picnic shelter and playground and the Lewis and Clark Interpretive Center. Other nearby amenities are the riverfront walking trail and public restrooms.
The Sergeant Floyd River Museum and Welcome Center serves the tri-state areas of Iowa, Nebraska and South Dakota as an information center. Uniquely it also serves as a historical museum as both functions are housed aboard the dry-docked motor vessel, the M.V. Sergeant Floyd. Admission is free.

The M.V. Sergeant Floyd, a decommissioned, inspection boat of the United States Army Corps of Engineers, was named in honor of Sergeant Charles Floyd, the only man to have died on the Lewis and Clark Expedition. A visit to the Sgt. Floyd provides visitors with valuable local information as well as a lesson in Missouri River history.

Accessibility: The Sergeant Floyd River Museum & Welcome Center is accessible on the first floor via a ramp; second floor is accessible via an elevator. The adjacent public restroom facility is accessible.

Volunteer opportunities at the Sgt. Floyd River Museum & Welcome Center
Support for the regular staff is provided through volunteers provided by the Retired Senior Volunteer Program (RSVP) and other programs. RSVP volunteers provide three hours of service per week. The Sgt. Floyd staff provides training for all volunteers. Duties include greeting and helping the visiting public, phone work, and gift shop sales. No prior experience is necessary, but a general knowledge of Sioux City, its history and points of interest are helpful. A volunteer can sign on a regular weekly basis or as a substitute. For more volunteer information, see the Volunteer section.

Two free annual events for the whole family are held each summer on the grounds of the Welcome Center: the Bill Diamond Antique and Classic Car Show and the Sergeant Floyd Memorial Encampment.
