The only store on the island is the Windigo Store, a small general store located near the ferry dock on the west end of Isle Royale. This store carries many types of food and supplies, but it’s best to bring most of your own provisions. All food sold on the island must be shipped in from the mainland, so that drives up the cost. However, it’s nice to know the store is there, so you won’t starve if you run low on food.
