The trailhead to Willow Lake is about 11 miles up Big Cottonwood Canyon and is on the north side of the road right after the passing lane begins. It can be easy to miss, and is only marked with a plaque on a rock (40.630302, -111.604639). As you hike a little in from the road you will see the trailhead. This hike is just under 1 mile, but is pretty steep. It eventually levels out the closer you get to the lake. Before you reach the lake you will come to a wide open field. Continue on and take the trail on the left.

Moose often hang around this lake, so keep an eye out. The colors in the fall are amazing, but the lake is fuller in the spring and summer. Wildflowers are also abundant in the summer months. Camping is allowed as long as you are 200 feet from the lake. Swimming is not allowed.
