Harbor to Hills Section 2: Hike from Three Mile to Daisy Farm

This stretch of the Rock Harbor Trail is Isle Royale at its most raw — a rugged shoreline scramble that threads between dense boreal forest and the cold, open waters of Rock Harbor Channel. You'll pick your way over slick rock shelves and gnarled root networks while the trail rises and dips with maddening frequency, never letting you settle into a rhythm. The payoff comes in layers: first the historic Rock Harbor Lighthouse appears through the trees, then the weathered structures of Edisen Fishery tell the story of the island's commercial fishing past. Overgrown vegetation crowds the trail in summer, so you'll feel the wilderness pressing in. By the time you reach the Daisy Farm campground, tucked along the harbor shore, you've earned every blister. This one is for backpackers who want their miles to feel like real miles, not a sidewalk stroll.
