Greenleaf Falls Trail is a 8.8 mile out and back trail located near Stevenson, WA that features a waterfall. The trail is rated as difficult and primarily used for hiking.
I would not label this trail difficult, but moderate. Overall, this hike was kind of boring; just miles of mud and mosquitoes. The mossy scree at the top was cool, with views of Table Mountain and the Two Chiefs. Hikers have boasted the view of the Columbia River Gorge from here, but the trees were too tall to see much. The Greenleaf Falls were pretty, but the Gorge is full of better waterfalls.
Hiked this trail in January so it was a bit muddy although easy enough to skirt around. Guidebook rated it as difficult but I see it more as moderate with the length being the main fitness challenge. There is about 1550 feet of elevation gain but it's a pretty steady climb without being too steep and not too many obstacles to circumvent. Beautiful forest but not much else to see until you reach the top. At the turning around point you get views of Mt. Hood, Bonneville Dam and the Columbia River. You also are at the base of Table Rock and the beautiful Greenleaf Falls.
