Sacajawea State Park

Sacajawea State Park is a 267-acre park situated where the Snake and Columbia rivers meet, featuring 9,100 feet (2,770 m) of freshwater shoreline. The park includes sand dunes, wetland ponds, and areas for hiking and boating activities.

The expedition group camped here from October 16 to 18, 1805, at this strategic river location. This was the group's first documented position in uncharted western territory.

The Interpretive Center displays exhibits about the expedition, Native American tribes, and artifacts linked to the Wanapum and Umatilla peoples. The exhibits help visitors understand how this place connects to the people who have lived in the region for generations.

Vehicle access requires a Discover Pass, and the park operates from April through October for visitors. You can spend time hiking, boating, fishing, or participating in organized group activities during your visit.

Seven circular installations by a renowned artist are spread across the grounds, displaying information about local plants and animals. These artistic displays allow visitors to explore the natural surroundings in new ways.
