Sacajawea Interpretive Center features displays on the Lewis and Clark Expedition through the eyes of Sacajawea. Particular emphasis is placed on the time the Corps of Discovery camped at the confluence of the Snake and Columbia Rivers from October 16th - 18th in 1805. Displays on the tribes they met at the site explore the importance of the land and resources of the area for the people who have called the confluence area home for thousands of years. The park also features a swimming beach, boat launch, picnic areas, and walking trails.
Also present in the park is one of a series of public art installations that make up "The Confluence Project" by celebrated artist, Maya Lin. Located in front of the Sacajawea Interpretive Center, the "Confluence Story Circles" celebrate the native cultures, languages, flora, fauna, geology, and natural history of the confluence of the Snake and Columbia Rivers.
