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 Historic Highway 30, from Ainsworth to Crown Point to the west, you'll find the world's greatest concentration of high waterfalls (like Multnomah Falls).

By leaving the park on Nesmith Point trail, you'll end up with a splendid view of St. Peter's Dome, a majestic basalt monolith rising 2,000 feet above the mighty Columbia River. Hiking is definitely something you'll want to do while camping at Ainsworth State Park.

Back at the campground, you'll find 45 peaceful full-service campsites canopied in a laid-back, tree-filled setting. There are also four walk-in tent sites for a more primitive camping experience. This is a classic campground ... the smell of a campfire is your constant companion. Flush toilets, showers, a camp host, firewood and an amphitheater with interpretive programs are all here. Top it off with a roaring creek at the east end of the park, and you have all the makings for a great camping trip.
History of the Area
Ainsworth State Park is located in the Columbia River Gorge National Scenic Area, Oregon. The park has a rich history that dates back to ancient times when Native American tribes inhabited the area.

Before European settlers arrived, several indigenous tribes such as the Chinook and Multnomah lived along the Columbia River. They relied on its abundant resources for sustenance and trade.

In 1805-06, Lewis and Clark Expedition explored this region during their journey across America's western territories. Their expedition brought attention to the natural beauty of Ainsworth State Park's surroundings.

During the mid-19th century, pioneers began settling in what would become Oregon state. In 1851, Samuel Cason established a homestead near present-day Cascade Locks (near Ainsworth). This marked one of many settlements by early pioneers who sought opportunities in agriculture and logging industries within this lush landscape.

The construction of railroads played an essential role in opening up access to remote areas like Ainsworth State Park. In particular, Henry Villard's railroad company built tracks through Eagle Creek Canyon around 1882-83 which allowed easier transportation between Portland and eastern regions including Hood River Valley where fruit orchards thrived due to favorable climate conditions.

Around this time period (late 19th - early 20th centuries), tourism started growing rapidly with people flocking from nearby cities seeking respite amidst nature's wonders offered by places like Ainsworth State Park - waterfalls cascading down cliffsides into crystal-clear pools below were particularly popular attractions drawing visitors' attention year-round!

By late twentieth-century standards though it became apparent how fragile ecosystems could be threatened if not properly managed; thus efforts ensued protect these lands while still allowing public enjoyment thereof: hence designation national scenic area status granted Congress under President Ronald Reagan signed law November1986 ensuring preservation future generations enjoy too!
