Isle Royale Seaplanes is the sole concessionaire offering seaplane transportation to Isle Royale National Park. Their main office and contact center is in Hancock, Michigan along the Keweenaw Waterway. Flights originate from there and from the Cook County Airport in Grand Marais, Minnesota. Both departure bases provide service to Windigo and Rock Harbor.
Throughout the operating season the seaplane's schedule varies; it typically operates from mid-May through mid-September. Overnight and day-trip visits are offered.
