Steamboat Toledo

Celebrating 150 Years, 1878–2028

Built in 1878, the sternwheel steamboat Toledo connected communities along the Cowlitz River and became an important part of the region's transportation history.

As the 150th anniversary of its maiden voyage approaches in 2028, GTHH is working to bring that history to life for a new generation through research, public programs, a large working model of the historic vessel, and plans for the anniversary celebration.

Looking beyond the anniversary, GTHH is also developing the concept for a Steamboat Theater & Museum—a distinctive community attraction inspired by the historic Toledo that would combine history, education, entertainment, and tourism.
