The U.S. National Parks are some of the best places to reconnect with nature, but lately, they have been more packed with tourists than ever—especially during peak seasons. If you’re like me, you like to visit National Parks to get away from the crowds, not join them. Luckily there is more than just Yosemite! The U.S. has 63 National Parks, many of which are unknown to the general public.
Here are three of the least-visited national parks that need to be on your radar this summer season. As someone who has visited nearly half of the U.S. National Parks, I can say with certainty that these three parks are both incredible and underrated, offering stunning landscapes, incredible wildlife, and solitude. P.S., Don’t worry—they don’t require long flights like those to Alaska, Hawaii, or American Samoa.

1. Dry Tortugas National Park, Florida
2023 Visitors: 84,285 (Ranked 55th busiest out of 63 National Parks)
Located 70 miles west of Key West, Dry Tortugas National Park is a breathtaking collection of small islands surrounded by crystal-clear waters. Despite being in Florida, one of the most tourist-heavy states, this park remains one of the least visited due to its remote location.
If you choose to camp on the island after the main boat heads back to Key West, you’ll find yourself in a perfectly private National Park. Just remember to pack in and out everything you need.
Why Visit?
- Historic Fort Jefferson – A massive 19th-century coastal fortress that once housed prisoners, including Dr. Samuel Mudd.
- World-Class Snorkeling & Diving – The park features pristine coral reefs and shipwrecks teeming with marine life.
- Secluded Beaches – Unlike other Florida beaches, the ones at Dry Tortugas remain uncrowded, offering a peaceful retreat.
How to Get There
You can reach Dry Tortugas via the Yankee Freedom ferry from Key West, a seaplane, or a private boat. The ferry ride takes about 2.5 hours one way.
Best Time to Visit
Spring (March-May) offers the best conditions for snorkeling and sightseeing, with warm waters and fewer storms.
Where to Stay
You can actually camp on the island! It makes for an incredible experience. But if you prefer to stay at a hotel and do a day trip, I recommend staying at Santa Maria Suites in Key West. It’s my favorite hotel in Key West.
2. North Cascades National Park, Washington
2023 Visitors: 40,351 (Ranked 57th busiest out of 63 National Parks)
Often overshadowed by Mount Rainier and Olympic National Park, North Cascades is a true wilderness wonderland just a few hours from Seattle. With jagged peaks, turquoise lakes, and glacier-covered mountains, it’s shocking that this park remains so under the radar.
Why Visit?
- Stunning Alpine Scenery – The park features over 300 glaciers and dramatic mountain views.
- Endless Hiking Trails – From easy scenic walks to challenging backcountry routes, there’s something for every level of hiker.
- Solitude & Wildlife – Unlike Washington’s more popular parks, North Cascades offers a true sense of solitude and is home to bears, mountain goats, and eagles.
How to Get There
The main access point is via State Route 20 (North Cascades Highway), which runs through the park. The nearest major airport is Seattle-Tacoma International Airport (SEA), about a 3-hour drive away.
Best Time to Visit
Visit between July and September when the snow has melted, and the full trail system is open. Fall also offers stunning foliage and fewer visitors.
Where to Stay
As usual with National Parks, the cheapest and most nature-full option is to camp! However, my favorite hotel I recommend near the park is Sun Mountain Lodge.
3. Isle Royale National Park, Michigan
2023 Visitors: 28,965 (Ranked 59th busiest out of 63 National Parks)
Tucked away in the northwest corner of Lake Superior, Isle Royale National Park is a true hidden gem. This remote wilderness is only accessible by ferry, seaplane, or private boat, which naturally limits the number of visitors.
Why Visit?
- True Wilderness Experience – With no roads and only backcountry trails, Isle Royale offers a unique, off-the-grid adventure.
- Incredible Wildlife – The park is home to moose, wolves, and a diverse range of aquatic life in the surrounding Great Lakes waters.
- Perfect for Backpacking & Kayaking – Over 165 miles of hiking trails and endless kayaking opportunities make this a paradise for outdoor enthusiasts.
How to Get There
The only way to reach Isle Royale is by ferry or seaplane from Michigan or Minnesota. Ferries depart from Houghton and Copper Harbor, MI, as well as Grand Portage, MN.
Best Time to Visit
Visit between late June and early September when the weather is warm, and all ferry routes are operational. The park is completely closed from November to mid-April.
Where to Stay
The Isle Royale National Park actually has a great hotel directly in the park called Rock Harbor Lodge. It is the only hotel in the park.
