  • Ainsworth is located in close proximity to Interstate 84 and a working rail line that operates day and night.

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 marks the eastern end of the popular "Waterfall Corridor" that stretches west to Crown Point and includes the majestic Multnomah Falls.

The shaded campground is the perfect jumping-off point for a hiking adventure. Hike the Nesmith Point trail for a splendid view of St. Peter's Dome, a majestic basalt monolith rising 2,000 feet above the mighty Columbia River.


Due to safety concerns caused by damage from the Eagle Creek Fire, the Gorge Trail 400 that connects Ainsworth and the forested area surrounding the campground is CLOSED.  Entering closed parks or trails may result in a citation, eviction, and/or exclusion from the park for up to a year.  

Please ask park staff about hiking opportunities in the area.  If you have questions please feel free to call the campground ranger at (503) 793-9885. For a complete list of open parks and trails in the Gorge, visit
