From the parking area outside of the closed campground, just doing the loop, I measured 1080' total elevation gain and 5.25 miles.

The trail is in great condition, dry and solid with few obstacles. The creek was rushing, and the yellow jackets thankfully appear to be dormant. 

Lots of dogs, but almost all of them were entirely kept on leash, love to see it.

Campground closed but adequate parking. Trail in very good condition and some foliage color with the maples that are present. This is a trail through the timber with lots of creek crossings via nice bridges. Recommend the side trail to Confluence with the small loop back to the upper Big Creek. Saw 6 other hikers and a couple of dogs. Note the climb seems higher than details for hike indicate, and with the extra distance through the closed campground, etc. this is more like a 5 mile distance. Note also that with campground closure the bathrooms are also closed. It was an enjoyable hike.

It was a beautiful hike on a gorgeous, well maintained trail. There is certainly plenty of work put into keeping this trail active and well used. We ran into some angry yellow jackets at around 2 miles if taking the counter clockwise direction. A stinging and biting session took place on the south end of a bridge that borders a large boulder. It is best to avoid the bridge altogether and scramble around the boulder at this time. Again, a lovely trail with some angry bugs right on the trail. I’m guessing this will not be an issue by winter.

Some small trees down on the trail from recent storms, easy to get around. Surprising amount of water in the creeks at the confluence; gorgeous as ever! Bathrooms at campground locked thus, no facilities. Lots of cars but saw few hikers on this late afternoon midweek outing. 

The upper loop trail (827.1) takes you in a few steps from the campground into the deepest woods!  Going clockwise, the trail splits at 1.9 miles with a choice to head up to Mt Ellinor, while this trail begins a slow descent for 2.5 miles along gorgeous cascades on the creeks and across picturesque bridges back to the campground.  There are plenty of log benches to rest or just absorb the beauty of the trail and waterfalls.  The trail is in perfect condition, and the return half does require a little bit of root and rock stepping but nothing that sneakers can't handle.
