Dillon Falls, Cascade waterfall in Deschutes National Forest, Oregon.

Dillon Falls are rapids on the Deschutes River in Deschutes National Forest near Bend, Oregon. They begin with a 15-foot (4.6 m) drop, then become steep Class-5 rapids with a hazardously placed tree in the center, before easing to Class 2 and 3. The falls are hard to see; trails give a somewhat better view.

Dillon Falls takes its name from Leander Dillon, a homesteader who settled near the rapids on the Deschutes River. He died in 1907, and the falls have carried his name since. The rapids lie in the Deschutes National Forest near Bend, Oregon.

The falls take their name from Leander Dillon, a homesteader who lived nearby and died in 1907. Because the lava slot muffles the sound and the river bends out of sight, the rapids are hard to see and hear from the calm water upstream, so visitors often rely on the trails for a view.

The area is accessed through the Dillon Falls Day Use Area with parking available, and a short trail of about 0.3 miles leads to viewpoints. Visitors should bring a Forest Pass and watch their footing on wet and slippery rock surfaces.

Dillon Falls is hard to see and hard to hear: the lava slot it cuts limits how much sound carries, so the river above the falls looks calm and wide. Warning signs there are easy to dismiss, yet on July 19, 2025, people were swept off the falls; one was found dead at the scene and two were declared missing.
