Nestled in the awe-inspiring Columbia River Gorge, Ainsworth is equal parts waterfall wonderland, hiker's playground and camper's delight. Situated at the eastern end of the Historic Columbia River Highway, the park also marks the eastern end of the popular "Waterfall Corridor" that begins at Crown Point and includes the majestic Multnomah Falls. Latourell, Bridal Veil, Wahkeena, and Horsetail Falls are also along this route.
The shaded campground is the perfect jumping-off point for a hiking adventure. Picnic tables, a plumbed restroom, and access to the Gorge 400 Trail and Horsetail Falls (#438) trail are located along three roadside parking areas a half mile west of the campground entrance.
