The 4.8-mile Island Mine Trail is an historical walk through much of the park's past. You could probably hike from Siskiwit Bay to the Greenstone Ridge in 3 hours or spend an entire day exploring artifacts in brush alongside the trail.

The trail is often used by backpackers to complete a 30-mile loop out of Windigo that includes the Feldtmann Lake Trail (8.5 miles), Feldtmann Ridge Trail to Siskiwit Bay Campground (10.3 miles) and the western portion of the Greenstone Ridge Trail back to Windigo (7.1 miles).

Others use the Island Mine Trail to depart the Greenstone Ridge for a night at Siskiwit Bay, adding an extra day to their cross-island trek. The hike from Siskiwit Bay to Windigo is 11.9 miles but Siskiwit Bay is worth it. Some have dubbed the spot "Riviera of Isle Royale" as it features warmer air and water temperatures than much of the park and has long stretches of red sandstone beach. The campground has two shelters, group and individual campsites, tables, and pit toilets, and a large dock.
