Directions from Salt Lake City: Follow Big Cottonwood Canyon Road (7000 South Wasatch Blvd.) about 4.4 miles up the canyon to trailhead. Trailhead is located on the north side of the S curve 0.1 mile past Mill B South Fork Picnic Area. Trailhead sign marks the beginning of the trail.
Kudos to whoever marked that little side trail that takes you to the rocky overlook, giving a gorgeous view of the canyon, almost 360 degrees around. This has been my favorite hike in my young career of hiking the wasatch.
There are a couple cool campsites close to the beginning of the trail
There is a waterfall 100 yards up the stream from the road. Take the small unmarked path next to stream just to the left of the trail on the north side of the road.
Shaded most of the way, easy enough for kids although the first part is a climb it does get easier. We packed out a lot of extra trash from careless people that built campfires too close to the trail. PLEASE practice "Leave No Trace" so others can enjoy the wilderness.
Great hike with the kids!
Hidden Falls is in the area and to see the waterfall follow the stream to the LEFT. The waterfall is just a few hundred feet back. We saw many unprepared people on Mill Fork B who made the switchback climb looking for the waterfall.
Mill Fork B trail is to the right. In the beginning ( approximately first 1/4 mile) this steep and can be labeled difficult with sun and switchbacks. After that you follow the trail along the stream and into a wooded and shady area for another moderate ascent that is relatively shaded. It is beautiful. Continue to climb up and to your write you will see a sloping rock crop that is a great place to break and enjoy a few of the Big Cottonwood Canyon. My group continued a little more to the valley overlook and then turned back. This trail is not as popular a Lake Blanche so if you are looking for a good hike, views, and to get away from the populace it will not disappoint.
Beautiful, shaded, lots of trees and water. Not crowded early in the morning.
Steady climb for the first 4 miles, lots of switchbacks. When I went in late May, there was some snow patches after about 3.5 miles. After 4 miles, at the last stretch along the east side of the mountain, the snow was too deep and difficult for me with regular hiking gear. Some steep snow patches and obstacles that made the trail indistinct in places, so it's helpful to use the GPS. A little muddy in places, but agile feet on the rocks should keep your shoes clean.
FYI: At the junction, this trail follows the sign towards Mill A Basin.

One of my favorite trails to hike when I want a leg stretcher. There are a few variations to add length to this hike.
One can go east on the trail at the first junction and wrap around above Maxfield Basin and on to Mill A or beyond.
This trail is beautiful. Pretty steep the first 1/4 mile then turns to a nice moderate grade. The trail is pretty clear with a few logs to hurdle and some muddy snow & water areas.
We saw a moose just before the lookout along the ridge. My 2 boys (4 & 6) loved this hike. We didn't make it to the top due to time but would definitely do this one again.
Amazing trail in every way.
Hiked two miles up and got stopped by a snow bank that obscured the trail and looked to dangerous to cross, so I returned the way I came. The small waterfall, just off the trailhead was nice and the wet weather creek was running strong so I got serenaded for quite a distance. The biggest disappointment was road traffic was present almost all the way. Had some nice views.
I started up the Lake Blanch trail when I got back to the parking lot.
It's an awesome hike with great view from the top
