The boat ramp at Washington Harbor sees steady traffic all summer, but most of those boats keep moving past Grace Island toward the larger campgrounds on the main island. That's the point. Grace Island Campground sits on its own small island outside Washington Harbor, on the southwest end of Isle Royale National Park, and with only two sites and a three-night stay limit, it rewards people who plan ahead and don't mind a little solitude. Here's what you need to know before you go.
Getting to Grace Island
There is no ferry service to Grace Island. This is a campground you reach by your own boat - canoe, kayak, or private watercraft. The dock sits in 2 to 4 feet of water under normal conditions, which means kayaks and smaller boats have no trouble pulling in, but deeper-draft vessels should approach cautiously. The harbor can get choppy in afternoon winds, so early morning crossings tend to go smoother.
Keep an eye out for the Middle Islands Passage buoy, which as of 2026 is off course. Rangers at the visitor center recommend favoring your chart and depth sounder over the buoy's position until the NPS gets it reset. This is one of those details the park complete visitor guide mentions briefly, but experienced boaters will tell you it matters more than the notice suggests.
The campground is open from April 16 through October 31 annually, operating 24 hours a day. In practice, most visitors arrive between June and September when Lake Superior is less likely to test your judgment.
Campsites and Shelter Setup
Two shelters are available, and that's your only option - there are no tent pads or designated tent sites separate from the shelters. First-come, first-served, no reservations accepted. The shelters are basic: three walls, a roof, a raised wooden floor. They keep the worst of the weather off you, but they won't keep the bugs out at dusk.
What to expect from the shelters
Each shelter sleeps about four people if you're friendly, or two if you want to spread your gear out. The floor is rough wood - bring a sleeping pad thick enough to smooth out the uneven planks. There are no mattresses, no electricity, and no heat. Pack your sleeping bag rated for the temps you'll actually see, not the ones you hope for. Lake Superior pulls cold air across the island even in August, and nights in the 40s are not unusual.
Site selection
With only two sites, your choice is essentially "east or west." The dock side shelter tends to get more foot traffic from people pulling in to check the campground before deciding whether to stay. The far shelter offers marginally more privacy but sits closer to the tree line where the mosquitoes hold their evening meetings.
Food Storage Rules You Cannot Ignore
The NPS has updated food storage guidelines for 2026. In response to wolves accessing human food and garbage around Rock Harbor and the east end of the island, new rules are in effect across the park - Grace Island included. This means:
- All food, trash, and scented items must be stored in approved bear-resistant containers or hung properly.
- Coolers left unattended on the dock or outside the shelter will attract attention. It might be a fox, it might be something larger.
- Cook away from your sleeping area. Wash dishes at the dock, not next to your shelter.
Rangers will tell you that wolves on Isle Royale are generally not a threat to people, but a fed wolf is a dead wolf, and the park service is serious about preventing that outcome. The fine for improper food storage isn't the real consequence - the real consequence is being the reason a wolf gets habituated and subsequently removed.
What You Actually Do Here
Grace Island is not a destination for people who need activities. There are no ranger programs, no gift shop, no maintained hiking trails on the island itself. You come here to be on the water.
Paddling around Washington Harbor
The sheltered waters around Washington Harbor offer decent paddling when the wind behaves. The southwest end of Isle Royale sees less boat traffic than Rock Harbor, so you'll have stretches of water to yourself. Carry a chart - the harbor has shallow spots and submerged rocks that don't show up on satellite views.
Fishing
Lake Superior fishing near Grace Island can be productive. Lake trout and whitefish move through the area. You'll need a Michigan fishing license, which is required for all waters in and around Isle Royale National Park. The dock is a fine spot to cast from at dawn, when the water lies flat and the surface feeding picks up.
Watching the light change
This sounds like brochure language until you've actually watched sunset from the southwest end of the island chain. The sun drops behind the open lake, and the water turns from gray to orange to a deep purple that lingers for twenty minutes. From this overlook you can see the length of Washington Harbor darken as the mainland fades into a single dark line on the horizon.
Practical Logistics for a Grace Island Stay
Stay limit and timing
Three nights maximum from June 1 through Labor Day. Outside that window, the stay limit is more flexible, but the weather is also less predictable. Most visitors do one or two nights and move on.
Water and waste
There is no potable water on Grace Island. You bring every drop you need. Plan on at least one gallon per person per day - more if you're paddling hard or the weather turns warm. There are no flush toilets. The vault toilet at the campground is basic and sees limited maintenance. Pack out all toilet paper and hygiene products.
Cell service
Cell service drops out well before you reach Washington Harbor. Do not expect to make calls, send texts, or check weather apps once you leave Houghton. This is a backcountry experience, not a glamping trip with connectivity.
Most visitors underestimate how isolated Grace Island feels. You can see the main island from the dock, but the water between you and it is cold, deep, and capable of turning dangerous fast. The park service recommends filing a float plan with someone on the mainland and checking in when you return.
What the Website Does Not Tell You
The official NPS page for Grace Island lists the basics accurately enough. What it does not mention is that the campground fills early on summer weekends, and the only way to know if a site is open is to paddle over and check. No phone service, no reservation system, no way to call ahead. You either commit to the crossing or you don't.
Experienced visitors know to arrive at Washington Harbor before noon if they want a reasonable shot at a shelter. Boats that roll in at 4 PM are often turning around to find somewhere else to camp.
What to Bring
- Bear-resistant food container (required under current guidelines)
- Water filter or purification tablets as backup
- Sleeping pad thick enough for wooden shelter floors
- Headlamp with fresh batteries
- Full change of clothes in a dry bag
- Michigan fishing license if you plan to fish
- Chart of Washington Harbor and surrounding waters
- First aid kit with foot care supplies - the dock and shoreline are rocky and uneven
- Stove and fuel - no fire rings or designated fire areas are mentioned for this campground, and fire conditions change seasonally

- The Middle Islands Passage buoy is off course. Navigate by chart, not by marker.

Final Thoughts
Grace Island Campground is not for everyone. If you want amenities, book a room in Houghton. If you want solitude, quiet water at dawn, and the feeling of having a Lake Superior island to yourself for a few nights, this campground delivers. The margin for error is thin - water supply, weather windows, and shelter availability all demand respect - but that is exactly why the place works the way it does. Two shelters, three nights, no backup plan. Plan accordingly, pack carefully, and the island will treat you well.
