Campsites at Grace Island Campground (2026 Guide) (2026 guide)

Most boat-in campgrounds on Isle Royale are scattered along the eastern side of the island, which means the ones on the southwest end see far less traffic. Grace Island Campground sits on its own small island outside Washington Harbor, with two shelters and a dock that can handle overnight boat tie-ups. The stay limit of three nights from June 1 through Labor Day keeps turnover moving, and since there are only two sites, you will want to plan your approach carefully.

This is not a campground you stumble upon. You need a canoe, kayak, or private boat to reach it, and the dock depth runs only two to four feet under normal conditions - shallow enough that larger vessels will need to check their draft before pulling in. If you are working through a complete visitor guide for Isle Royale and weighing which campgrounds fit your itinerary, Grace Island is worth considering if you want the southwest end without the crowds that Rock Harbor draws.

The Arrival: Getting to Grace Island

Grace Island sits outside Washington Harbor on the southwest end of Isle Royale National Park. This is not a location you reach on impulse. The island is accessible only by private boat, canoe, or kayak - no ferry service drops passengers here. The designated dock provides overnight tie-up for boaters, but the depth at the dock under normal conditions is shallow: two to four feet. That means a deep-keel sailboat or a large powerboat with a significant draft may have trouble getting close enough to tie off. Kayakers and canoeists will find the shallow approach manageable, especially in calm weather.

The campground is open from April 16 through October 31 annually, operating 24 hours a day during that window. The park closes entirely from November 1 through April 15, so plan your trip within the operating season. As of 2026, there is no entrance fee for small-party camping of six people or fewer - you just need a free overnight permit, which you pick up before heading out. No reservations are accepted. All sites are first-come, first-served.

What the Park Website Does Not Mention

The official materials will tell you the dock and shelters exist. What they do not emphasize is how exposed this campground feels compared to the more sheltered sites on the main island. Grace Island is a separate landmass, and weather can pin you here longer than intended. Boaters familiar with Lake Superior know that the southwest end catches wind sweeping across the entire lake. If a storm system moves in, that two- to four-foot dock depth suddenly matters less than whether you can safely launch at all. Experienced visitors build a buffer day into their itinerary when staying here.

The Sites and Layout

Two shelters. That is the entire campground. There are no RV pads, no electric hookups, no water spigots, and no dump station. You are camping on an island with exactly what you carry in and out.

The shelters provide basic protection from wind and rain, but they are not insulated cabins. Bring your own camping gear. There is no potable water on Grace Island - you must filter or treat lake water, or pack your own. The park service recommends treating all surface water before drinking.

Food Storage Rules - Pay Attention Here

As of the 2026 season, the park has new food storage guidelines in response to wolves accessing human food and garbage around Rock Harbor and eastern-end campgrounds. While Grace Island is on the southwest end, these rules apply park-wide. Store all food, garbage, and scented items in bear-proof containers or properly hung bear bags. Wolves on Isle Royale have learned that campers sometimes leave food accessible, and once that behavior starts, it is difficult to reverse. Rangers will tell you this is not just about your safety - it is about keeping wildlife wild.

What You Actually Do Here

Grace Island is not a destination for amenities. You come here for isolation, for the kind of quiet that settles in after the boat engine cuts off, and for access to the waters around Washington Harbor.

Paddling and Boating

The primary activity is moving on the water. The southwest end of Isle Royale offers protected paddling around Washington Harbor and the nearby islands when conditions cooperate. Early morning is your best bet for flat water before the afternoon winds pick up. Kayakers should be comfortable with open-water crossings and have solid self-rescue skills. Lake Superior does not forgive complacency.

Fishing

The waters around Grace Island hold lake trout and whitefish. Anglers need a Michigan fishing license, which applies to Isle Royale waters. Check current regulations before you go - some areas have seasonal closures or gear restrictions.

Wildlife Viewing

Keep an eye out for moose swimming between islands - it is not uncommon to see them crossing channels in summer. Loons call across the water at dawn and dusk. Bald eagles nest along the shoreline of the main island. The wolves that prompted the new food storage rules are present on Isle Royale, though you are unlikely to encounter them on Grace Island itself. They travel the shorelines and may swim between islands.

What Most Visitors Underestimate

The challenge here is not the camping. It is the logistics. Pack extra water for this stretch - you will need more than you think, because cooking, drinking, and cleaning all draw from your carried supply unless you are treating lake water. The distance from Houghton (where the park headquarters is located at 800 E. Lakeshore Drive) to the southwest end of Isle Royale is significant. You need to factor in travel time, weather windows, and the reality that cell service drops out at the dock and does not return until you are well offshore heading back to the mainland.

Planning Your Stay

When to Go

The campground operates April 16 through October 31, but realistically, the shoulder months are cold. Most visitors target June through August, which aligns with the three-night stay limit period starting June 1. Late August and early September offer warmer water temperatures and fewer insects, though the water never gets truly warm by Lake Michigan standards.

What to Pack

• All food in bear-proof containers
• Water treatment system (filtration or chemical)
• Camping stove and fuel - no firewood on the island
• Rain gear and wind layers
• Navigation tools - paper charts and compass, not just your phone
• First aid kit with supplies for minor injuries
• Overnight permit (free, required)

The Permit Process

You obtain your free permit at the park visitor center before departing. The permit covers your entire itinerary, so you need to know which campgrounds you plan to use and on which nights. Rangers will ask about your route, your experience level, and your equipment. They are not being nosy - they are making sure you have what you need to stay safe. Talk to them honestly. If you are uncertain about any part of your plan, they will offer practical advice.

Practical Takeaways

1. Call ahead. Contact the park at 906-482-0984 or email isro_parkinfo@nps.gov to check current conditions before you head out. Dock depth, weather forecasts, and any active advisories can change your plans.

1. Arrive early. First-come, first-served with two sites means the early arrival claims the shelter. If both are taken, you are boat-camping or moving to another location.

1. Treat all water. No potable water on Grace Island. Filter or boil lake water, or pack your own.

1. Respect the three-night limit. June 1 through Labor Day, you get three nights maximum. Plan your route accordingly.

1. Store food properly. The wolf population has learned to associate campers with food. Use bear-proof containers and follow the park's current storage guidelines exactly.

1. Build a buffer day. Weather on the southwest end can shift fast. Having an extra day in your itinerary prevents you from making unsafe decisions trying to beat a storm.

Final Thoughts

Grace Island Campground is the kind of place you pick deliberately. It rewards self-sufficient boaters who know what they are doing on Lake Superior and who value solitude over convenience. The two shelters, the shallow dock, the absence of anything resembling a store or a ranger station - none of that is a flaw. It is the point. If you want the full list of all campgrounds on Isle Royale to compare your options, the park website has a complete rundown. But if you already know you want the southwest end, quiet water at dawn, and a site that forces you to be self-reliant, Grace Island will deliver exactly that.
