Did hike as a trail run in late April - 2hrs - easy to moderate - rolling hills, some steep downhills and some steep uphills, but mostly rolling or flat. Spectacularly beautiful - incredible waterfalls, lush forest/fern hillsides, interesting canyon setting. Trail took you behind several waterfalls - under cave-like rock outcropping - very cool. We started at the Silver Falls Lodge trailhead, but noticed several other potential starting points, like at the Winter Falls trailhead or the North Falls trailhead. We did loop clockwise, which takes you past waterfalls in first half of hike (approx 3 miles), with second half of hike not as stunningly scenic, but still nice and woodsy. Hike starts at top of canyon rim, goes down, makes ascent up out of canyon, then along rim trail for 2nd half. Trail mostly dry, with a few muddy patches (it had rained several days prior). We ate our picnic lunch at a picnic table near the river after finishing up. Lodge had a little snack bar with hot dogs and hot beverages. Cute gift shop where they sell weiner/marshmellow roasting sticks. Picnic tables around river - had grilling grates for BBQ. Great hike, great day. Would highly recommend. Trail was slightly crowded, but places of extreme beauty often are. Wasn't wall to wall, but was not a solitary experience.
