Things To Do


Sacajawea State Park is a 284-acre inland waters, day-use park at the confluence of the Snake and Columbia rivers. It features 9,100 feet of freshwater shoreline. The area is spread out with a big sky and excellent views of the two rivers as they flow together. The park has many outdoor self-guided interpretive displays, as well as framework representations of Native American dwellings. Along with the on site Interpretive Center, the park provides guided tours by a park interpretive specialist. The property was deeded to Washington State Parks in 1931. The park is named for Sacajawea, a Shoshone Indian woman who traveled with the Lewis and Clark expedition. The park is located on one of the expedition's campsites, used by Lewis and Clark from October 16 to 18, 1805. The railroad built the town of Ainsworth in 1879. By 1884, the town was no longer used, and the buildings were moved or destroyed as local construction of the railroad was completed and the crew moved on.
