The largest Island in Lake Superior and one with a varied history, Isle Royale National Park is one that most people (even freq. National Park visitors) know little about. The park started life with ancient Ojibwe history from generations ago. With European settlers the area became known for mining which later turned into a resort for wealthy Michiganders.
Fishing and resort life declined considerably on the island and in 1940 the Island became a National Park. Following its new designation, exploitation of minerals, trees ended, and the few remaining settlers were moved off the Island.

About Isle Royale
The 45 mile long (9 mile wide (at its widest point) National Park is located in the middle of Lake Superior and incredible when you forget that it’s situated within a freshwater body. The main island is surrounded by almost 400 islands from ones that are tiny to more medium and larger sized islands. The park is generally open seasonally from April 16 through October 31 and hosts many plant and animal species. Many of which are surprising to find on the island such as Moose and Wolves.
These days, the island has some remains of its mining, fishing, and resort history, but much of the island now is designated as wilderness. Over 90% of the land is considered wilderness and exploration and camping requires a backcountry permit. The island boasts being a National Park, UNESCO International Biosphere Reserve, Historic Site, National Wilderness, and a Minong (the Ojibwe name for the Island) Traditional Cultural Property.
The park is one of the least visited National Parks in the United States, and boasts the fewest visitors of any National Park in the contiguous United States (lower 48 states). But it is known as one of the Parks the most frequent revisits. Follow along to learn what to do and why you should visit. This remote National Park, while closer to Minnesota, is completely within the state of Michigan.

Things To Do
Hiking is the most popular activity at the park. There are miles of scenic hiking trails that crisscross through the islands. If you are only staying for the day, pay attention to times for the hikes as you need to be back to the boat to leave. Below are a sample of popular trails to explore:
Grace Creek Overlook: Windigo: 3.5 miles; 1.5- 2.5 hours. Offers beautiful views over grace creek, and lake superior. One of the “highest” points on the island. Good place to snack and enjoy the views.
Windigo Nature Trail: Windigo: 1.2miles; 30 minutes: Easy Nature trail with boardwalks in parts. Recommend getting a guide from the visitor center or take a ranger-led hike.
Minong Ridge Overlook: Windigo: 6.6miles 3-4 hours: Moderate Trail with some nice overlooks over the lake and area. Can be done as a day hike but you need to walk fast.
Scoville Point (Stoll Memorial Trail): Rock Harbor: 5 miles; 2 hours; Moderate trail taking hikers through wooded lands, rocky areas near Rock Harbor. Trail ascends to Scoville Point for views of the area.
Greenstone Ridge Trail: 40 miles; 16+ hours: Windigo to Rock Harbor: this is the most direct route overland between Windigo and Rock Harbor. Popular for cross-island hikers. Most visitors take 3-5 days to complete.
Boating is a popular activity on the island. Some areas of the park are only accessible by private water vessels. You can arrive to the island by boat, or you can also bring small watercraft with you aboard some of the ferries.
Be sure to check with the ferry as you may need to make a reservation that allows you to carry a water vessel board. Kayaking and canoeing are very popular in the National Park.
There are multiple shipwrecks within the boundaries of Isle Royale National Park, and visitors have the opportunity to dive and visit the wrecks as part of their visits.
Diving Lake Superior is challenging and requires specialized equipment and experienced divers. Lake Superior waters are cold all year round, drysuits are recommended.
There are no services for divers on the island, you need to bring all equipment, air filling, etc with you to the island. Additionally, due to Isle Royal being one of the most remote national parks, emergency services are limited and/or unavailable.
Major wrecks are buoyed to allow mooring for vessels for diving wrecks. Check with visitor centers on current conditions before mooring/diving.
Permits: Divers are required to register prior to diving at Rock Harbor, Windigo, or Houghton Visitors centers. Permits must be kept on-hand and returned after completion of the visit.
There is excellent fishing within Isle Royale as well as the coastal areas around the park.
For fishing in Lake Superior, you’ll need to have a Michigan fishing license. This includes bays and harbors along the land. You can purchase a Michigan License online or in stores.
Fishing at inland lakes of the park does not require a license.
There are however, a lot of regulations to fishing in Isle Royale. Be sure to check the Isle Royale Fishing Regulations for more information.
Camping is a popular activity on the island and one of the best ways to explore and experience Isle Royale National Park. Camping on the island does require a free backcountry permit to stay overnight. Be sure to collect a permit at either Rock Harbor, Houghton, or Windigo. Check out our camping section for more information.
Stargazing is a popular activity on the island with some beautifully clear nights. Isle Royale is incredibly remote with little light pollution, so you’ll be treated to great stars and occasionally views of the Northern Lights. You’ll need to camp to experience stargazing here.

Lighthouses of Isle Royale
There are 4 lighthouses that served Isle Royale over its history. The following are descriptions of the lighthouse.
Rock of Ages Lighthouse
One of my favorite Lighthouses, with an incredible history, architecture, and definitely the best name. Rock of Ages is worth a visit even from afar.
Unfortunately while I was visiting Isle Royale, the Lighthouse was undergoing restoration. I did get to meet several of the restoration team who were also visiting Isle Royale at the same time I was.
Built in 1908, the lighthouse is a feat of engineering. Built on a small islet just outside Washington Harbor, the 117 foot lighthouse seems impossibly perched on the small rocky outcropping in the lake. The total cost for construction was 125,000 far higher than the Rock Harbor Lighthouse and quite expensive for the time. The light from the lighthouse on a good day can be seen for up to 29 miles away.
The lighthouse saw operation until 1977 with a lighthouse crew that resided at the lighthouse. These jobs were very lonely and isolating but incredibly important to shipping through the region.
The Rock of Ages Lighthouse is often seen from boats traveling from Grand Portage to Windigo.
Rock Harbor Lighthouse
Built in 1855, the lighthouse and tower has sat on the Isle Royale guiding boats through the foggy weather of the great lakes. In the mid-1800s following the Treaty of LaPointe with the Chippewa Indians, the exploitation of copper and wood on the island accelerated. With the increased boat traffic, the needs of a lighthouse on the Island was determined necessary.
Rock Harbor lighthouse was the first to be built on the Island, costing approximately $5,000 at the time with a light visible for up to 14 miles away. However, the mining on the island was short-lived, with the lighthouse going in and out of service for a period of approximately 25 years. Years later the island saw visitors come for parties and exploration, with a family living in the early part of the 1930s.
However, since the establishment of the National Park, the lighthouse has stood inactive and mostly a point of interest for visitors to the National Park.
The Rock Harbor Lighthouse is generally a stopping point (to view) for boats from Copper Harbor, Michigan to Rock Harbor or for boats traveling from Rock Harbor to Windigo.
Passage Island Lighthouse
Located on the Northeast side of the Island, the lighthouse was built to guide boats between the main Isle Royale Island and Passage Island. Passage Island is a remote island at the extreme end of Michigan within Lake Superior (close to the Canadian Border) and often a point where boats traveling between Canada and the United States will pass. This is why the lighthouse is an important fixture for transit within Lake Superior. This passageway was considered quite dangerous for boats passing through this “gap”.
Completed in 1882, this lighthouse became the most important light within the Isle Royale chain of Lighthouses. It primarily serviced boats traveling from Thunder Bay Ontario and Sault Saint Marie, Michigan. Built for approximately $18,000 the lighthouse was manned through the 1950s and these days is still in operation however it is fully automated.
This lighthouse is generally not visited, and can only really be reached/seen by private vessel. The lighthouse itself is not generally open for visits.
Isle Royale Lighthouse
Built in 1875, the Isle Royale Lighthouse services the south side of Isle Royale at the entry to Siskiwit Bay. The 61 foot red-brick lighthouse stands watch on the small rocky islet of Menagerie Island.
In good weather and on a good day, the light from Isle Royale is visible up to 10 miles away. The lighthouse was built to support shipping to the island during the copper boom. Entry into Siskiwit bay is particularly dangerous and tricky and with the importance of mining and operations in the bay the lighthouse construction was authorized.
The lighthouse still operates, however like most lighthouses, it is fully automated. The lighthouse is not visited by any of the tour/ferry boats that visit Isle Royale and is only reachable by private craft.
Animals of Isle Royale National Park
There’s a diverse animal population within the islands of Isle Royale. Some you’ll have a good chance of viewing, with many others being rare but exciting to witness. We wanted to cover some of the amazing fauna you’ll find within the National Park
The American Marten is a small weasel-like mammal that is known to inhabit lands within the northern areas of North America (north US and Canada). Martens were hunted extensively in many areas of the west for their fur in past generations. Martens used to be very plentiful in Isle Royale although they seemingly disappeared suddenly from view. There were sightings even after they were believed to have been completely gone from the island. More recently however, there were efforts to repopulate martens to the island. And while it works, they are very shy and difficult to view in the wild.
The Park Rangers when I visited had an interesting “What Happened to the Marten” presentation. Sort of a “who-done-it” mystery.
No one is sure exactly how Moose arrived on Isle Royale, the prevailing theory is that they either swam across or walked across an ice bridge to reach the island. There are certainly ice bridges that form in Lake Superior on occasionally very cold winters.
The Moose population tends to fluctuate over the decades. But there is quite a healthy Moose population on the island with current estimates over 2000 moose. Several areas of the Island are known for Moose sightings, Washington Creek, Ojibway Lake, Feldtmann Lake, Hidden Lake (Tobin Harbor).
Wolves have been part of the Isle Royale landscape for generations. However, in more recent times due to human settlement, disease, food scarcity and other reasons the wolf population has declined. In addition there was concern with the genetic diversity of the remaining Wolves. In 2018 and 2019, Wolves from Minnesota and Ontario were relocated to the National Park to help bolster the population and genetic makeup of the wolf population.
Wolves are an important part of the landscape of the Island and help to control various other populations such as the moose on the island. There are currently 28 wolves recorded in the National Park.
Formally one of the most prolific creatures in this area of the world, beavers have certainly lost many of their numbers over the years. Beavers are the largest rodent in North America, and can grow to weights over 30lbs. You’ll often notice beaver activity by their dam constructions.
Beavers on Isle Royale are known to work around the streams and lake areas building their dams which make important habitats for other animals on the island. There are several thousand beavers believed to be on the islands and hundreds of beaver ponds that have been created by them.
The elusive red fox is the few canines within the National Park. These smart creatures can be seen throughout the island but tend to be shy and solitary for much of their life. They are most often seen on trails or close to campsites. Foxes tend to be about 14-20 inches tall and 18-35 inches long. They have a pretty distinct look so are easy to identify.
Red foxes are scavengers and will eat human food, please don’t feed them.
The playful otters are a plentiful creature in the bays and streams of lake superior. Members of the weasel family, the Northern River Otter can grow upwards of 40 inches long and 30 lbs in weight. Otters tend to be more adept at swimming and spend most of their life in and around the water.
There’s a healthy population of otters within Isle Royale although I couldn’t find recent population figures. Popular spots to see otters include along rivers and shores of the islands of Isle Royale.
There are lots of other animals to witness on the island that make up the ecosystem here. Including snowshoe hares, muskrats, white-tailed deer, bats, bald eagles, turkey vultures, coyotes, skunks, weasels, and more.
Tips & FAQs for Isle Royale NP
