We would like to go to Isle Royale for an overnight camping trip, but there are only 2 of us, and I read that you only take reservations for groups of 7 or more.
Parties of 6 or less are defined as "individual parties", meaning that reservations cannot be made. Parties of 6 or less, unlike groups, do not have to follow their permit's itinerary. Permits are obtained on the Ranger III en route to Isle Royale, or at the Rock Harbor or Windigo Visitor Centers upon arrival with other transportation providers. Groups of 7 to 10 must obtain advance reservations, must camp in group campsites, and must stick to their itinerary.

What are my chances of getting a campsite during the busy season?
Isle Royale's busy season is from mid-July through mid-September. Visitors should expect busy, crowded conditions at campgrounds and docks during this time. If campsites are full, we ask that you share with another camping party. The sites are large enough to accommodate multiple tents and people.

Can I bring my service dog to the island?
Service dogs are welcome on Isle Royale. However, a service dog permit must be obtained prior to your trip. Obtaining this permit involves receiving the proper paperwork from the park, consulting a licensed veterinarian no more then 15 days prior to your park visit, and having the permit signed by the park superintendent or representative.

Are there certain park tours that are better than others?
Which tours will fit your needs best really depends on you. How vigorous an excursion do you want? How long do you want to be involved? Evening programs are quite popular at Rock Harbor and Windigo, as they provide a time to learn about Isle Royale after a day of exploring. Short talks and nature walks work well for day visitors and those wanting less strenuous activity. Guided tours to Passage Island and Lookout Louise are good for those with a half a day who want to stretch their legs and seek a new view or knowledge.
