The Columbia Gorge Scenic Area has many trails east of Portland, Oregon and Vancouver, Washington. There are too many trails to list here and there are many websites that do a great job of detailing everything there is to know about each trail. Multnomah Falls is by far the most popular area to visit as it is close to big population areas. Trails further east are drier but have ticks, lots of poison oak, and of course, rattlesnakes. But when the wildflowers are in bloom late spring, the eastern Gorge can't be beat for amazing color and flower variation.
