Trail guide
The short Stoll loop follows the first signed crossover and returns before the route continues toward Scoville Point. Plan about 1 to 2 hours for roughly 1.8 miles. Longer options continue around the figure-eight or out to Scoville Point.
The Tobin Harbor side is mostly wooded and smoother, while the Rock Harbor side is rockier and more exposed. Boardwalks and steps break up the footpath, and wet rocks can be slippery. A steep slope leads down to a bridge near the Rock Harbor trailhead.
Interpretive signs along the route introduce Isle Royale’s natural and cultural history. The nearby Smithwick Mine is an early copper-mining site; its fenced rocky opening lies by the Tobin Harbor side trail access.
Start on the Rock Harbor side just past the Recreation Hall and the Lodge Ojibway building. Rock Harbor is reached by boat or seaplane, not by road, so plan around seasonal transportation. Pets are not allowed.
