Sacajawea Historical State Park
2503 Sacajawea Park Road

Imagine standing at a place where Native American people encountered the Lewis and Clark Expedition on its westward journey.

On Oct. 16, 1805, the Corps of Discovery arrived at the confluence of the Snake and Columbia rivers, the site of today's Sacajawea Historical State Park. They camped for two nights amidst a thriving community of Native American

As most Washingtonians know, a Shoshone woman named Sacagawea* was instrumental in the Expedition's success. Not only did she work alongside the men, she was an interpreter and an emissary of peace between the white explorers and Native American tribes.

Central to the park named for her is the Sacajawea Interpretive Center. Open April 1 to Oct. 31, (call 509 545-2361 for hours), the museum features interactive exhibits on the Corps of Discovery, Sacagawea and the Sahaptian-speaking tribes of the region. Stroll the green, tree-shaded grounds, and read the seven story circle installations by internationally known artist Maya Lin.

Once you've absorbed this fascinating history, head for the beach. Depending on the season, hundreds of birds flock to these inland waters, and boaters enjoy the two rivers, while kids play on the lawns and parents relax.

As evening falls, stand on the riverside, and picture the area as it must have been in 1805. If you weren't a Lewis and Clark buff before, you may find your curiosity piqued by this interesting park.
