What to Expect

This is Isle Royale at its most remote and unvarnished. From Lookout Louise, you'll push southwest along the Greenstone Ridge through dense boreal forest where the trail occasionally dissolves into a tangle of roots and rock. The path is lightly traveled enough that you'll spend as much time reading the landscape as following a clear tread — expect stretches where the corridor narrows and blowdowns demand creative routing. The forest opens periodically to reveal Lake Superior stretching to the horizon, and on clear days the Canadian shore materializes like a rumor. Mount Franklin's modest summit delivers panoramic ridgeline views that feel earned precisely because nobody else is up there. This stretch rewards hikers who treat navigation as part of the adventure, not an inconvenience.

Safety Advisory

The trail is poorly defined in several sections with roots, rocks, and minimal blazing. Losing the path is a real possibility, especially in fog or rain — strong map-and-compass skills are essential, not optional.

Isle Royale is wolf and moose territory. While wolf encounters are extraordinarily rare, moose are large, unpredictable, and surprisingly common along the Greenstone Ridge. Give them a wide berth, especially cows with calves in spring and early summer.

Pro Tips

Trail Tip

Arrange a water taxi or the MV Sandy drop-off at Lookout Louise rather than hiking in from Rock Harbor — it saves significant mileage and lets you start fresh at the remote end of the ridge.

Trail Tip

Carry a real map and compass, not just your phone. Cell service is nonexistent on Isle Royale, and the trail's faint sections will have you second-guessing intersections that a GPS track alone won't clarify.

Trail Tip

The stretch between Lookout Louise and Mount Franklin catches golden hour light beautifully from the ridgeline clearings — time your hike to be on the exposed sections in late afternoon for the best views across Lake Superior.
