Greenstone Section 6: Hike from Ishpeming Tower to South Desor
What to Expect
Safety Advisory
Trail conditions change significantly between early and late season — what was a clear path in July can be nearly swallowed by vegetation by September, making navigation skills essential rather than optional.
Isle Royale has no emergency vehicle access. An injury on this remote section means a long carry-out or a wait for float plane evacuation, so hike with a partner and carry a PLB or satellite communicator.
Moose frequent these hardwood corridors, especially near water sources at dawn and dusk. Give them at least 50 yards and never position yourself between a cow and calf.
Trail Details
Pro Tips
Carry a physical map and compass as your primary navigation tools — GPS signal is unreliable on Isle Royale, and this section's overgrowth can obscure trail blazes for stretches at a time.
Pair this section with an overnight at South Desor campground to break up the Greenstone Ridge traverse; trying to rush through as a day segment leaves no margin for route-finding slowdowns.
Wear long pants and gaiters regardless of temperature — the overgrown vegetation along the trail hides shin-level obstacles and the brush harbors ticks throughout the summer months.
