Day Boaters

Boaters who are in the park for one day, and who do not overnight, do not need a permit. However, as Lake Superior is an unpredictable lake, a day permit is recommended. Call (906) 482-0984.

Day boaters must pay entrance fees and receive an orientation at Houghton, Windigo, or Rock Harbor upon arrival.

Overnight Boaters

Isle Royale National Park requires a permit for all boaters who overnight in campgrounds, at dock, or at anchor. Boaters need to permit in advance by calling (906) 482-0984 unles traveling on the Ranger III. You will get your boater permit on the Ranger III on your trip over.

Permits issued in advance are emailed to the requester and require printing, signing, and having visible on your vessel at dock and on any tent or shelter while camping. Digital permits are not accepted. If you are unable to print your permit prior to departure, proceed directly to Windigo or Rock Harbor to obtain a printed copy of your permit.

Please return your permit upon conclusion of your trip to any visitor center in person or through the mail (address is listed on the permit). Update any changes from your planned itinerary. Tracking use in this manner helps the park prioritize dock and campground maintenance.

Fees & Passes

Private boaters must pay entrance fees the same as all other visitors. The Isle Royale Season Pass is typically the most cost effective method of payment.
