Considered by many to be one of upper Michigan's most picturesque waterfalls, Agate Falls is located on the middle branch of the Ontonagon River. 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. Access to view the falls is via an improved, accessible foot trail. Parking, water, toilets and picnic tables are available at the park, which is generally open from early May through late October.
