Isle Royale National Park
Isolated by the chilly waters of the largest freshwater lake on earth is a richly forested island of volcanic rock that we call Isle Royale National Park.
It is a world apart, a uniquely secluded northern wilderness where the ruthless delicacy of nature's balance is an observable fact.
This 45-mile-long refuge, some 15 to 18 miles from Canada and about 50 miles from the Michigan mainland, is one of the few places in the lower 48 states where wolves run free and unchallenged.
Playing as they once did across much of the Northern Hemisphere, a vital role in maintaining the health and strength of the wildlife community they prey upon.
About Isle Royale National Park
Isle Royale National Park is located in the northwest region of Lake Superior. While the park technically belongs to Michigan, its location makes it easily accessible from Canada and Minnesota, in addition to the state’s Upper Peninsula.
The park’s remote island location does make it a bit difficult to access, and visitors will need to take either a boat or seaplane out to the island.
In addition, the park is only open for part of the year due to extreme weather (mid-April through late October).
The park is a prime example of undeveloped north woods wilderness and offers very little in the way of modern conveniences.
This is a national park for true adventurers - keep reading to find out more!
Is Isle Royale National Park worth visiting?
Isle Royale is the least visited national park in the lower 48, but that doesn’t mean that you should count it out.
Although the park’s remote location deters most, it is absolutely worth making the trek.
Of all the national parks in the system, Isle Royale has the most repeat visitors. Those who have been to the park know that this hidden gem is worth exploring again and again.
If you decide to make the journey out to Isle Royale, you will be rewarded with unspoiled wilderness, epic hiking trails, hundreds of lakes to fish from, and a gorgeous shoreline that can be explored by canoe or kayak - all without the crowds!
History of Isle Royale National Park
Although Isle Royale has been a protected area for nearly a century, its history goes even further back.
Native Americans used the island for fishing and hunting, and there is evidence of copper pits used to create tools and weapons from this time period as well.
Once Europeans came to the island in the early 1800s, copper mining and commercial fishing were widespread, but are no longer present today.
In 1931 the island and submerged land surrounding it became a national park, and in 1981 Isle Royale became an international Biosphere Reserve.
Even with the presence of mining and commercial fishing operations, the island has remained mostly untouched by the outside world and is one of the best examples of primitive America.

Insect repellent is always a great idea outdoors, especially around any body of water.
We use Permethrin Spray on our clothes before our park trips. Please read my article on preventing biting insects while enjoying the outdoors.
Sunscreen - I buy environmentally friendly sunscreen whenever possible because you inevitably pull it out at the beach.
Bring your water bottle and plenty of water with you. Plastic water bottles are not sold in the park.
Sunglasses - I always bring sunglasses with me. I personally love Goodr sunglasses because they are lightweight, durable, and have awesome National Park Designs from several National Parks like Joshua Tree, Yellowstone, Hawaii Volcanoes, Acadia, Denali, and more!

Binoculars/Spotting Scope - These will help spot birds and wildlife and make them easier to identify. We tend to see waterfowl in the distance, and they are always just a bit too far to identify them without binoculars.

However, note that Lake Michigan is notorious for its unpredictable weather and its rocky bottom and coastline, so proceed with caution!
Best time to visit Isle Royale National Park
Isle Royale is the only park in the entire system that closes down completely for part of the year, so you’ll need to plan your trip between mid-April and late October.
Of course, the weather is at its best in the summer months, and you’ll never have to worry about crowds, but the shoulder seasons have their own appeal as well.
Weather and Seasons
Spring
The park is closed until mid-April, but once the snow begins to melt, the park begins to come alive again with wildlife and visitors.
One of the perks of visiting in the spring is that there are very few visitors on the island, and you’ll also beat the annual mosquito and black fly hatching that occurs in late May.
However, note that the weather may still be a bit iffy in Spring, so check the weather forecast before making any solid plans.
Summer
Your best shot for warm sunny days in the summer, though even these months can be chilly, windy, and stormy.
July is typically the warmest month at the park, though temps rarely reach above 75 degrees Fahrenheit.
Plan for chilly weather and wear plenty of layers as you won’t have much reprieve from the elements on this remote island.
If you visit in the summer, you should also pack plenty of bug spray to ward off the mosquitos and black flies that hatch in late May.
Autumn/Fall
Autumn can be a great time of year to visit the park, especially when the fall foliage is at its peak.
However, temperatures are quite chilly during this time of the year, so plan accordingly. Visitors should also note that the park closes completely on November 1st each year.
Winter
Isle Royale National Park is completely shut-down in the winter (November 1st to April 15th).
Best Things to do in Isle Royale National Park
Wildlife viewing
Wildlife viewing at Isle Royale National Park is unlike any other place on earth. About 99% of the land area is designated wilderness, which means that it has been protected from outside influence.
The most common wildlife sightings at the park include red fox, loons, moose, snowshoe hare, beaver, mink, marten, red squirrel, and river otter.
In the late 1940s, temperatures dropped so low that an ice bridge formed between Isle Royale and Canda, allowing a small pack of Eastern timber wolves to make the crossing.
Their numbers are extremely low, and you probably won’t see any during your visit, but their existence in the park is pretty incredible and worth noting.
Junior Ranger Program
If you brought the kids along on your trip to Isle Royale National Park, be sure to sign them up for the junior ranger program.
This hands-on program will allow your young ones to learn all about the park in a fun way, and once they complete the program, they will receive a cool badge to commemorate their time here.
Fishing
Fishing has long since been a part of the island, and Native American tribes once fished from these very waters.
There are over 100 inland lakes across the island, and you can fish from these permit-free.
Common catches include walleye, trout, northern pike, and perch. If you want to cast out on the big lake (Lake Superior), you’ll need to obtain a Michigan fishing license before arriving at the park.
Paddling
Paddling is a great way to see some of the hidden nooks and crannies of the park.
The most popular area for paddling is around Rock Harbor, and you can rent kayaks and canoes from the Rock Harbor campground or Rock Harbor Lodge. You could also bring your own water vessel along on the ferry for an additional charge.
Guided Boat Tours
If you want to make sure you stay dry while exploring the park, you can book a sightseeing tour with the MV Sandy.
Park rangers lead various different tours around the shoreline with opportunities to disembark and participate in guided hikes.
Tours are available between early June and early September.

Greenstone Ridge Trail - Hard - 43 miles - Point to Point

The best part about this lengthy trail is that it traverses nearly the entire length of the island, so no matter where you are in the park, it's relatively easy to hop on and hike a section.
Mount Franklin via Tobin Harbor Trail - Moderate - 9.4 miles - Out & Back
This popular route follows Tobin Bay along the rocky coastlines. The views are epic, and it’s not uncommon to spot moose and other wildlife along the trail near the pond!
Scoville Point via Stoll Trail - Easy - 4.7 miles - Loop
This is one of the easiest trails at the park, so if you want stunning lake views without all the work, this is one of the best options.
Minong Ridge Overlook - Moderate - 6.6 miles - Out & Back
Don't miss the Minong Ridge Overlook if you’re on the west side of the island (Windigo area). This is a moderately difficult route that ends at the scenic Minong Ridge Overlook.
Hikers will be rewarded with panoramic views of the island’s west end and Lake Superior. On clear days you can even see Canada’s shoreline in the distance.
How to beat the crowds in Isle Royale National Park?

If you prefer the security of knowing where you’ll rest your head at night, book a room at the Rock Harbor Lodge, located on the northwest side of Isle Royale.
The rooms are a bit dated, but if you want a real bed and a great meal waiting for you after a long day of hiking or paddling, the Rock Harbor Lodge will do splendidly.
Windigo Camper Cabins
There are also two cabins available for rent on the southwest side of the island.
These rustic, one-room cabins are a great retreat from the elements, though they do get booked up extremely quickly each year. So, be ready to book in January for the coming season if you want to snag one of these abodes.
