Located in Lake Superior, this remote park can only be reached by ferry, private boat, or float plane. Visitors are also only permitted to visit from April through October due to Lake Superior’s harsh winter conditions, making it one of America’s least-visited national parks.

The best way to experience Isle Royale is to spend a few days or even a week exploring its pristine wilderness with your backpack.

Hike over 40 miles along the Greenstone Ridge Trail and take in stunning panoramic views of the island terrain with Lake Superior in the distance.

You may even spot some wildlife while you’re out there – keep an eye out for the island’s resident moose population! We were able to watch a female moose enjoying an evening meal in one of the inland lakes for quite some time, from a distance.

If you decide to stay overnight, there are only primitive campgrounds available within the park and no cars on the island.

Otherwise, you’ll have to snag a room at the Rock Harbor Lodge. A day trip isn’t really enough time to get a sense of the beauty of the island, and we’d absolutely recommend camping.

And don’t forget: some nights tend to be cool here, even during the summer months, make sure to bring warm clothing with you if you plan on stargazing! 

6. Acadia National Park, Maine

Acadia National Park in Maine is a must-visit for anyone looking for the perfect summer getaway on the east coast. With its stunning views of the Atlantic, this park is sure to take your breath away.

Take in the beauty of this national park on foot by exploring one of its many hiking trails. The Beehive Trail is one of the most popular trails, as it takes you up ladders to reach breathtaking views from atop granite cliffs. It can be difficult for those who have a fear of heights, like me!

If you’re looking for something a little more relaxed, hop on a bike and explore Cadillac Mountain Road – it’s the perfect way to enjoy the park at a more leisurely pace, during a 3-mile ride to the top of the tallest mountain in the park.

Of course, no summer visit to Acadia National Park is complete without spending some time at the beach! Sand Beach and Echo Lake are the two most popular spots. Make sure to bring plenty of sunscreen, though, as temperatures can get very hot during peak season, even though the water is often still chilly!

While summer may not be the best time to see the Northern Lights, there is a chance you can see them in Voyageurs National Park if conditions are right.

While camping on the shoreline of one of the many lakes and waterways is a beautiful way to spend the night in the park, you can also rent a houseboat and there are campsites specifically arranged to dock them, so you can enjoy a little luxury while in a remote location. It’s quite the contrast!
