Where else would you get a chance to swim in the Sandy River where Pacific Northwest explorers Lewis and Clark probably washed their clothes? This was one of the expedition's camps around 1805. It is the western end of the Columbia River Gorge/Mount Hood Loop, where the river is widest with huge banks. Folks today probably like the park for more recreational reasons, including the beach access, swimming and fishing. With some incredible views of the Cascade Mountains, this is a good stop if you are touring the Gorge. The park is free and open all year.
