Arnold Mine Falls

There's a small gravel parking area on Eagle Harbor Cut-Off Road, marked "Monk Trails" on Google Maps (coordinates 47.418116, -88.226032). From Eagle Harbor, it's 4.7 miles along the Eagle Harbor Cut-Off Road.

About 0.5 miles one way from the Monk Trails parking. The trail climbs steadily and can be muddy until late spring. Alternatively, you can hike up Jacob's Creek from Jacob's Falls on M-26, which is a steeper 0.7-mile route that links both waterfalls.

Yes — the ruins of the 1860s Arnold copper mine sit just above the falls. The mine operated until 1900 and produced nearly two million pounds of copper before closing. The stone structures are open to explore, but watch your step around the old shaft openings.

It's not the most dramatic waterfall in the Keweenaw — only about 4 feet tall — but it's one of the least-visited, and the trail itself is the draw: hand-carved wooden benches built by the monks, the historic copper mine ruins, and a quiet creek-side walk through Holy Transfiguration Monastic Park. Pair it with Jacob's Falls and the Jampot bakery for a full afternoon.

No. The Society of St. John's Monastic Park trails are free to use. The monks maintain the trails themselves and the property is open to the public for hiking.
