Isle Royale’s Wolf Population Causes Campground Closures

Imagine going on a remote island vacation only to get your luggage aggressively rifled through by the local wildlife. That is exactly what is happening at Michigan’s Isle Royale National Park, where a few wolves decided to skip the hunting and go straight for the room service, according to MLive. Campers learned the hard way that a flimsy mesh screen is no match for a hungry predator when a wolf or wolves “accessed the interior of a shelter by tearing, scratching and pushing through the screen,” leaving a trail of dragged laundry and chewed-up coolers in their wake.

Park officials tried blasting air horns and even firing paintballs to teach the animals some manners, but Liz Valencia, the park’s acting administrative officer, admitted that “efforts earlier this month to deter wolf activity at the Duncan Narrows Campground through a shorter closure and increased hazing were ineffective.” As a result, sections of this water-access-only paradise are officially locked down for the month while rangers try to get the local packs to stop treating campsites like free buffets.

What makes this so crazy is the concentration of the wolves. Isle Royale is a tiny, isolated archipelago in Lake Superior, home to just about 37 wolves. To put that into perspective, the state of Montana is home to an estimated 1,100 wolves, according to the Montana Department of Fish, Wildlife & Parks. While Montana has vastly more wolves roaming, and many Big Sky sportsmen believe there are even more than that, Isle Royale’s small population is packed onto a tight, isolated island chain, making human-wolf run-ins way more intimate. Because the island’s wolves have reached their highest numbers in 50 years, the stakes are high for everyone to play by the rules. Park Superintendent Denice Swanke summed up the ultimate goal for the summer: “Visitor safety and the protection of wildlife are our highest priorities. We ask for your support in securing food, trash and scented items consistent with 2026 food storage guidelines.” Follow the rules, or prepare to watch a wolf jog down the trail with your favorite backpack.
