Hidden Falls

 Hidden Falls is a small waterfall in Big Cottonwood Canyon. The short trail features a narrow canyon with a pretty forest, a mine shaft, and of course a nice waterfall.

We had a full day at the Big Cottonwood Brew Fest so I just wanted something a little short and easy, so, this is where we ended up. We have been here a couple of times, but it’s been a minute since we were here so why not.

Quick Details:

Length: About 3/10ths of a mile out and back, depending on how much you explore.
Trail Type: Out and back, or a spur off of the Mill B North Trail.
Difficulty: DR3. It is a little rocky, but it is super short.
Elevation Gain: About 100 feet.
Restroom: Yes, at the Mill B South Trailhead.
Dogs? No. Big Cottonwood Canyon is watershed.
Other Info: This is now a fee area. $10.00 day use fee.

To Get Here:

Drive about 4.4 miles up Big Cottonwood Canyon to the big S Curve. Park in the smaller upper parking lot. The trail picks up across the road to the north.

The Trail:


Trailhead kiosk.



Short little trail up to the road.


Then we have to scramble across Big Cottonwood Canyon Road. It is a super awkward spot next to the S curve, so be super careful.


Into the woods!

It doesn’t look like it goes very far back but yeah, I don’t think I need to find out for sure.

Here you can see why they got that name.

I first learned about these in Yellowstone. They grow around the geysers there. They don't seem very picky, just like wet. I read that they even grow out of mineral rich streams coming out of mines.

There is a short paved trail, it leads to a couple smaller waterfalls and it also leads to the Lake Blanche Trail.

That was a fun quick little add on! I love all waterfalls, so it is nice to have a couple that are easy to get to. We only ran into 1 other couple and it was a nice bonus because we swapped taking pictures for each other. I am taking a squirrel for the scramble across Big Cottonwood Canyon Road. 9 out of 10 squirrels.

As for difficulty, It is short, but rocky. DR3.

Dogs are not allowed in Big Cottonwood Canyon, so be sure to leave Fido home.
