"Rainforest Canyon." Taken in Oneonta Gorge, Oregon. Apparently it's just a few miles east of Multnomah Falls on the historic highway. The hike is great for all ages that can walk and it's about a half mile, but straight up a river and has a cool log jam. The canyon only gets about an hour of daylight to the floor, so if you want any warmth, start the hike at 11:45-12:15ish. There's a giant waterfall at the end, with a pool you can swim in.
The Oneonta Gorge is in the Columbia River Gorge in the American state of Oregon. The U.S. Forest Service has designated it as a botanical area because of the unique aquatic and woodland plants that grow there. - http://www.theworldgeography.com/2013/04/gorges.html
