Summary: Essential map for hiking Isle Royale
Review: This map is part of the Trails Illustrated series covering many national parks. These are all sturdy and convenient.

Your map choices are essentially this one, the National Park Service map, and USGS topos. The NPS map is fine if you're staying at Rock Harbor Lodge and doing light day activities from that base.

If you're backpacking, or doing long day hikes, the Trails Illustrated map is absolutely essential because the USGS topographic maps are outdated. For example, the topo shows a no-longer-existent East Feldtmann trail on the southwest part of the island.

The topo also shows inaccurately the trail that goes over White Oak Ridge in the same area. The Trails Illustrated map shows the trails correctly.

This map also shows (1) group and individual campsites and (2) distances between trail junctions that accord with the NPS signage. Both features make it useful for planning your trip.
