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.
