Columbia River Gorge
For Multnomah Falls, I started in the less crowded Wahkeena Falls parking lot and finished the loop at the famous waterfall (5 miles, 1600ft "Loop #2")
Wahclella Falls
Triple Falls
Silver Falls State Park
The Trail of Ten Falls is the longest hike in Silver Falls State Park with South Falls probably being the highlight. The trail can be split up into sections, although the full loop is fairly easy for an eight mile hike with minimal elevation change. I had good luck with it the month of March.
Middle North Falls
Lower North Falls
North Falls
Abiqua Falls
There is a short hike to Abiqua Falls, which was surprisingly crowded on a rainy Wednesday afternoon in March. The dirt road to the trailhead took a couple attempts in one spot coming back, but a normal car can handle it
Smith Rock State Park
There are some places to sit and watch climbers on Monkey Face on the Misery Ridge loop. The loop can be finished with the shorter and easier river walk or a longer hike along the Summit Trail
