Moose sightings are extremely rare in the lakeshore although tracks and scat are occasionally found. The wetlands and cedar swamps of the park, particularly in the Beaver Basin Wilderness, are likely moose habitat. Black bear wander throughout the park and are seen only infrequently, usually when crossing a road. Other large mammals documented in the lakeshore but rarely seen include bobcat and badger. American marten and fisher were extirpated from the Upper Peninsula by the 1930's but have made a comeback with the help of reintroduction programs. Northern river otter numbers have increased as well in recent decades. Beaver are common in the park and their activities are noticeable in many locations near streams and ponds. A lucky hiker may come across a porcupine or snowshoe hare in the backcountry. Coyote and red fox are present throughout. Opossum have been moving north and may already be in the area. Of the park's many smaller mammals, chipmunks are most commonly seen.
