Doughnut Falls, Mountain waterfall in Big Cottonwood Canyon, United States.

Doughnut Falls is a waterfall in Big Cottonwood Canyon, south of Midvale in Salt Lake County, Utah. The stream plunges into a pothole, and visitors can enter under the arch of rock to look up at the falls dropping into the pool. Access is from the Mill D Trailhead toward the Jordan Pines picnic area.

The waterfall became part of the Wasatch-Cache National Forest trail system as the region developed its hiking network during the mid-20th century. The rock formation itself was shaped by natural geological processes over thousands of years.

The name comes from the doughnut-shaped pothole the water drops into. Visitors climb up the waterfall itself to reach the cave behind the arch and look up at the falls pouring into the pool.

Access starts at the Mill D Trailhead toward the Jordan Pines picnic area. In summer the hike is about 1.5 miles round trip, but parking spots are scarce. In winter an alternative path to the often frozen falls can run up to 3.5 miles round trip, and the last stretch means climbing up the waterfall to reach the cave.

In winter the waterfall often freezes, and reaching it then requires an alternative path of up to 3.5 miles round trip, compared with about 1.5 miles in summer. After the hike, visitors must climb up the waterfall itself to reach the cave behind the falls.
