The Unique Geology of Donut Falls
What makes Donut Falls truly special is its distinctive geological formation. Over thousands of years, water from Mill D South Fork Creek has carved a circular hole through the limestone cliff, creating what looks like a giant donut. The water flows through this natural tunnel before plunging about 20 feet into a small pool below.
The “donut hole” itself sits about 10-15 feet above the base of the falls. During peak runoff seasons (typically late spring), the water volume is so high that it can completely fill the donut hole, making it less visible. For the best view of the actual donut formation, late summer and early fall visits are recommended when water levels are lower.
The surrounding canyon features quartzite and limestone formations that date back millions of years, with the entire area shaped by glacial activity during the last ice age. The result is a picturesque setting with dramatic cliff faces and smooth, water-polished rocks that create the perfect backdrop for this natural wonder.

Getting to Donut Falls Trailhead
The Donut Falls trailhead is located in Big Cottonwood Canyon, about 9 miles from the mouth of the canyon and approximately 20 miles southeast of Salt Lake City.
Driving Directions
From Salt Lake City, take I-215 to the 6200 South exit and head east toward the mountains. This road becomes Wasatch Boulevard and then Big Cottonwood Canyon Road (Highway 190). Drive approximately 9 miles up Big Cottonwood Canyon to the Mill D Trailhead.
At the Mill D Trailhead, turn right toward the Jordan Pines picnic area. Follow this road past some summer homes until you reach the Donut Falls parking area. During summer weekends, this lot fills quickly, so arrive early or be prepared to park at the Mill D Trailhead and walk the additional distance.
Parking Tip: During summer weekends and holidays, the parking lot often fills by 9:00 AM. Consider visiting on weekdays or arriving early to secure a spot. A National Forest Pass is required for parking, which can be purchased at the trailhead or online.
The Donut Falls Hiking Experience
From the trailhead, you’ll follow a well-marked path that begins as a wide dirt road before narrowing into a traditional hiking trail. The route follows Mill D South Fork Creek for much of the way, providing pleasant stream views and the soothing sounds of running water.
The first portion of the trail is relatively flat with a gentle incline, making it an easy warm-up. As you continue, the path gradually climbs through a beautiful forest of aspen and pine trees. During summer, wildflowers dot the landscape, while fall brings spectacular foliage colors.
About a mile into the hike, the trail becomes slightly steeper as it approaches the falls. You’ll cross a wooden bridge over the creek and continue up a short incline. The final approach to the falls involves some light scrambling over rocks, but nothing too challenging for most hikers.
Once you reach the base of the falls, you’ll see water cascading down a rocky slope. To view the actual “donut hole,” you’ll need to look up at the cliff face where the water emerges from the circular opening. For the best view, there’s a small viewing area at the base of the falls.
Trail Navigation Tip: The trail is well-marked and easy to follow, but there are a few side paths that can be confusing. Always stay on the main trail and follow signs for “Donut Falls.” If you’re hiking in winter, orange markers on trees help guide the way when snow covers the trail.
Best Seasons to Visit Donut Falls
Donut Falls offers a different experience in each season, making it a year-round destination for outdoor enthusiasts. Here’s what to expect throughout the year:
Spring (May-June)
Spring brings powerful water flow as mountain snow melts. The falls are at their most dramatic, but the “donut hole” may be less visible due to high water volume. Trails can be muddy and slippery.
Summer (July-August)
Summer offers warm temperatures and accessible trails. Wildflowers bloom in mid-July through early August. This is peak tourist season, so expect crowds, especially on weekends.
Fall (September-October)
Fall brings spectacular foliage as aspen trees turn golden. Water levels are lower, making the donut hole formation more visible. Cooler temperatures make for comfortable hiking conditions.
Winter (November-April)
Winter transforms the falls into a frozen wonderland. The trail becomes a snowshoe route with the falls often partially frozen. Special equipment and experience are recommended for winter visits.
Photography Tips for Donut Falls
To capture the best photos of Donut Falls, consider these tips:
- Early morning or late afternoon light provides the best illumination for photographing the falls
- Bring a polarizing filter to reduce glare from the water and enhance colors
- Use a tripod and slow shutter speed to create that silky water effect
- For winter photos, increase your exposure compensation to prevent snow from appearing gray
- The best view of the actual “donut hole” is during late summer when water levels are lower
Safety Considerations at Donut Falls
IMPORTANT SAFETY WARNING: Several fatalities have occurred at Donut Falls from people slipping on wet rocks. The rocks around and under the falls are extremely slippery. Do NOT attempt to climb up to the donut hole or on the steep rock faces surrounding the falls.
General Safety Tips
- Wear appropriate footwear with good traction
- Stay on designated trails and viewing areas
- Keep children closely supervised at all times
- Bring plenty of water, even for this relatively short hike
- Check weather forecasts before heading out
- In winter, be aware of avalanche conditions in the steep canyon
The final approach to the falls involves some rock scrambling that can be challenging for very young children or those with mobility issues. Consider viewing the falls from a distance if these sections seem too difficult.
