Charbonneau Park in Eastern Washington was named one of America's Top 100 Family Campgrounds. It is located on Lake Sacajawea, formed by Ice Harbor Lock and Dam on the Lower Snake River. The park was named for Toussaint Charbonneau, an interpreter for Lewis and Clark and husband of Sacajawea, the famous Shoshone interpreter on the Corps of Discovery. The park provides excellent recreational opportunities for boaters, campers, upland and waterfowl hunters and anglers.
The lake provides great boating and swimming opportunities, and a boat ramp is provided for guests. Fishing is also a popular pastime, and anglers will find excellent salmon and steelhead fishing on the lake.
The campground is situated on the banks of Lake Sacajawea, and several of its waterfront sites have scenic views of the lake. The park is characterized by its open grassy areas dotted with a few large shade trees.
From Pasco, Washington, take Highway 12 east. After crossing the Snake River Bridge, take the first exit and proceed to Highway 124. Continue east through Burbank, Washington. Turn north on Sun Harbor Drive and follow for 1.5 miles, then take a left on Charbonneau Road. Campground is on the right.
