Brockway Mountain Drive is a 9.5 mile scenic route in the Keweenaw Peninsula of Michigan just west of Copper Harbor. Access to the road is gained from M-26 from either Eagle Harbor to the west or Copper Harbor to the east. The drive runs along a cliff on the Keweenaw Fault and climbs to a height of 1,328 feet above sea level, 726 feet above the surface of Lake Superior. Several turnouts along the route allow for views of Copper Harbor, Lake Superior and undeveloped woodland.

This route is a must see for snowmobilers planning a snowmobile trip to the Keweenaw Peninsula.
