There is a ferry that goes to the island. So it would cost your gas, food and whatever lodging you require. Camping is available, not sure of the cost, there are hotels, the resort and cabins on the island. If you want a nice cabin look into Papin's. PAPIN\\\\\\\\\\'S
Or you can stay in a normal hotel in the Soo.
Then the ferry ride is 8 bucks for 1 rig and the driver, 2 bucks for any passangers.
If you trailer then it is an additional 12 bucks for a trailer up to 20 foot, or something like 15 bucks for a trailer over 20 foot.
No ORV sticker is required.
It's looking more and more like I am going to put a trail ride together for the end of May to go out there if you are interested.
