Sacajawea Historical State Park

Sacajawea Historical State Park: Where Two Rivers Meet at the Crossroads of American History

Sacajawea Historical State Park preserves the exact confluence of the Snake and Columbia rivers in Pasco where the Lewis and Clark Corps of Discovery camped for two nights in October 1805. This 267-acre day-use park combines profound historical significance with modern recreational opportunities, featuring the acclaimed Sacajawea Interpretive Center that showcases the meeting of cultures between the expedition, Sahaptin-speaking Native Americans, and the legendary Shoshone guide Sacagawea. With 9,100 feet of freshwater shoreline and interactive exhibits by internationally known artist Maya Lin, the park offers visitors a chance to stand where American expansion history was made while enjoying boating, fishing, and interpretive experiences along two of the West’s most important rivers.

Sacajawea Historical State Park Fast Facts

Park Overview

Sacajawea Historical State Park stands at one of the Pacific Northwest’s most historically significant locations, where the mingling waters of the Snake and Columbia rivers symbolize the gathering place of many peoples and cultures throughout the millennia. For thousands of years, Sahaptin-speaking tribes used this confluence as a traditional gathering, fishing, and trading place, with some people remaining through winter at this popular seasonal destination. The dramatic Ice Age floods that once covered this area under 800 feet of water in the temporary Lake Lewis basin created the geological foundation for what would become a crossroads of American history.

The park’s modern incarnation began through the dedication of the Daughters of the Pioneers of Washington in 1927, who hand-carried buckets of water to nurture trees marking the original Corps of Discovery campsite. Their efforts led to state park designation in 1931 and the construction of the interpretive center and supporting buildings by the Works Progress Administration in 1938. Today, visitors can explore the same shorelines where Lewis and Clark met 200 Native Americans, traded goods, and prepared for their final push to the Pacific Ocean.

Activities & Recreation

The Sacajawea Interpretive Center serves as the park’s crown jewel, featuring interactive exhibits where visitors can touch historical artifacts, listen to Native American songs, and experience hands-on demonstrations of traditional tools like bows and pestles. The center operates Wednesday through Sunday from April through October, offering interpretive programs year-round by appointment. Seven story circles installed by internationally renowned artist Maya Lin provide outdoor interpretation opportunities throughout the tree-shaded grounds.
