Hidden Falls in Big Cottonwood Canyon is a beautiful waterfall and is such a short walk that is accessible year round. It’s pretty with snow.
On years when there isn’t much snow, there is still a lack of plant life.
The trickiest part of this trail is that you have to cross the highway with limited visibility. It is right where the S-curve is in the canyon, next to the trailheads to Lake Blanche and Mill B South. I could see through the trees to know when cars would be coming, but it would be stressful with toddlers at a busy time. This first photo is next to the trailhead. This second photo is a few minutes into the trail, looking down on the S-curve.
Here is a map. The falls are right after the S-curve when you are headed up the canyon.
The parking lots at the Mill B and Lake Blanche trailheads aren’t plowed in the winter, so you will probably have to park along the side of the road. On the top side of the S-curve you can see the trailhead.
In the summer and fall you can walk along the path on the right side of the water. In the winter the snow makes that tricky. You may need to cross the stream to the trail on the other side.
Within one or two minutes you will see the waterfall ahead.
The waterfall is about the same size as Rocky Mouth Falls, but with a much shorter trail. Because Big Cottonwood Canyon is a watershed you shouldn’t play in the water. It’s such a short detour it’s a fun, quick stop.
This could be your destination, or you can stop on your way back from Lower Mill B North Fork Trail, Mill B South Trail or Lake Blanche. I recommend making this your last stop in case you accidentally get your feet wet.
