A Superior Adventure Worthy of Lake Superior.

Everyone has an inner sense of adventure, in search of new experiences and excitement. Now you can explore yours and arrive in style with an on-water landing that will punctuate the experience like nothing else can! Travel by seaplane to an island full of treasures and new experiences when you book your flight with Isle Royale Seaplanes from the Hancock Portage Canal Seaplane Base or Cook County Airport to Isle Royale National Park.

Isle Royale is the largest island in Lake Superior, measuring over 45 miles in length and 9 miles wide at its widest point. It is a portion of Isle Royale National Park along with several adjacent islands in Lake Superior. Formed as the glaciers receded over 10,000 years ago, it remains one of the most rugged and pristine wilderness areas in existence.

Explore a rugged, isolated island where wolves and moose abound,

far from the sights and sounds of civilization. Surrounded by Lake Superior, Isle Royale offers unparalleled solitude and adventures for backpackers, hikers, boaters, kayakers, canoeists and scuba divers. Here, amid stunning scenic beauty, you’ll find opportunities for reflection and discovery, and make memories that last a lifetime.

Isle Royale National Park is known for its wolf and moose populations which are studied by scientists investigating predator-prey relationships in a closed environment. This is made easier because Isle Royale has been colonized by roughly just one third of the mainland mammal species, due to its remote, isolated location. In addition, the environment is unique in that it is the only known place where wolves and moose coexist without the presence of bears.

There are usually around 25 wolves and 1,000 moose on the island, but the numbers change greatly year to year. To protect the wolves from canine diseases, dogs are not allowed in any part of the park, including the adjacent waters.

Reachable only by boat or seaplane, an Isle Royale adventure can only begin

once you cross a substantial portion of Lake Superior’s northwest section. Once there, one finds a living laboratory – a rugged, Northwoods wilderness of wild creatures, second growth forests, refreshing lake waters and pristine, scenic shores. This Island gem houses the highest backcountry overnight use per acre of any national park and at the same time it is one of the least visited. One visit here will foster a strong wilderness ethic and the desire to promote stewardship — all of which will serve to preserve and protect Isle Royale National Park for future generations.

The only thing separating us at the seaplane base in Hancock and KBC is the bridge! Lucky we operate in such a beautiful town!

Next time you see someone sipping’ a beer in KBC with an Isle Royale Seaplanes tee on, you should say hi! (They probably just got back from an epic trip! 😏) or it’s probably one of us! ☺️

There’s nothing better than watching Isle Royale’s shoreline disappear after a full week of Isle Royale adventure and bliss... once the shoreline starts to disappear— planning for the next Isle Royale trip begins!

What came first?
The beaver or the bridge?
If you guessed the beaver, you are correct! If you guessed the bridge, you are very close!

The Houghton-Hancock Bridge was constructed in 1959!

Our de Havilland Beaver was manufactured in 1952!
Two beautiful icons we are lucky enough to enjoy! ⠀⠀⠀⠀⠀⠀⠀
