Overview

The Indian Portage Trail is a classic interior route that runs north–south across Isle Royale’s wild heart, linking McCargoe Cove to Chippewa Harbor. It follows a historic Native American portage corridor once used to move birchbark canoes between the island’s inland lakes and coasts. Expect a varied backcountry sampler: quiet shorelines, beaver ponds and wetlands, short ridge climbs, and hushed conifer–hardwood forest. Point‑to‑point distance is just under 12 miles one way (roughly 19.6 miles if you plan it as an out‑and‑back). Difficulty is solidly moderate: no technical moves, but frequent ups and downs and rugged, uneven tread.

What You’ll See

This route stitches together some of the island’s most characterful inland waters, including Chickenbone Lake and Lake Richie, with junctions that let you touch Greenstone Ridge and other interior paths. Near the south end, bluffs above Chippewa Harbor deliver rugged, island‑studded views, and a short spur to Lake Mason leads to a scenic rock bluff. Along the way you’ll pass wetlands, old fire‑scarred forest from the 1936 burn, and glacially carved bedrock outcrops typical of Isle Royale’s greenstone ridges.

Wildlife and Trail Character

Wildlife is a real draw here: moose browse the lakes and bog edges, foxes work the trail corridors, and beavers stay busy in the ponds. Wolves are present on the island and are occasionally encountered in quieter interior sections. The tread is primitive—roots, rocks, and mud—with intermittent boardwalks through low areas. It’s well signed at intersections (portages are marked with “P” signs), but carry a real map and compass; GPS can be spotty under canopy and in remote sections.

Logistics and Camping

There’s no road access. You’ll reach the endpoints by boat or seaplane and start from the campgrounds at McCargoe Cove or Chippewa Harbor. Backcountry camping is available along the route, with popular options at West Chickenbone, Lake Richie, and Chippewa Harbor; the Chippewa Harbor shelters perch high with great views. Water is plentiful from lakes and streams, but there are no treated taps—plan to collect and purify, and check with rangers about any algal bloom advisories. Overnight backpackers must register an itinerary and obtain a backcountry camping permit before setting out. Pets are not permitted anywhere on the island’s trails.

Difficulty, Direction, and Pace

The mileage and the nonstop small climbs make this a respectable one‑day push for strong hikers, but most people split it into 1–2 days. Direction matters: the feel of the ascents and descents changes depending on whether you’re moving southbound from McCargoe or northbound from Chippewa. Expect sections to be slick and muddy after rain. Trekking poles and sturdy boots pay off here.

Best Time to Hike

Late spring through early fall (mid‑May to late September) is the window—outside of that, the park is closed. Early summer brings heavy mosquitoes and blackflies; late summer into early fall is usually kinder. For wildlife sightings and calm water reflections, move early or late in the day. This is a remote interior trail, so crowding is minimal even in peak season.

Who It’s For

If you want a genuine Isle Royale interior experience—history underfoot, lakes at your elbow, and a good chance of seeing moose—this trail delivers. It’s an excellent backbone for a backpacking loop or a north–south traverse that taps into the island’s long‑trail network.

Pros

  • Historic Ojibwe portage corridor with varied lakeside and ridge scenery
  • High, viewy shelters at Chippewa Harbor make a memorable finish or camp
  • Frequent natural water sources (with treatment) keep pack weights down

Cons

  • Early‑season mosquitoes and blackflies can be intense
  • Slick, muddy stretches after rain slow pace and hide roots
  • Long, quiet gaps between campgrounds require firm daily mileage plans

Parking

No road access. Arrive by ferry or seaplane; start at McCargoe Cove or Chippewa Harbor campgrounds via their docks.

Caution

Remote interior with long stretches between campgrounds; tread is rocky, rooty, and can be very muddy after rain. Treat all water and check with rangers for algal bloom advisories.
