Considered one of Michigan's most picturesque waterfalls, Agate Falls is located along the middle branch of the Ontonagon River. A half-mile trail provides access to an observation platform with views of the top of the falls. The trail passes through a tunnel under M-28 and you can also view overhead railroad trestles.
Parking, vault toilets, an adjacent paved trail and a picnic area are available at the adjacent Michigan Department of Transportation roadside park (generally open early May through late October).
The falls are created as the river finds its way over an extended shelf of terraced sandstone. The resulting waterfall is a broad band of interlacing cascades and small falls nearly 40 feet high. Visitors can access the observation platform via an accessible foot trail.
Depending on weather conditions, the site is typically open for vehicle access mid-May through mid-October. Trail access is open year-round; however, trails and boardwalks are not monitored or groomed for snow and ice.
