America’s national parks are often described as “crown jewels,” but the problem is — everyone wants to see the same jewels. Yosemite, Yellowstone, Zion, and the Grand Canyon are awe-inspiring, but they also attract millions of annual visitors. Long entrance lines, packed shuttle buses, and overbooked lodges can make your “escape into nature” feel more like a queue at Disneyland.
But here’s the secret: the U.S. is filled with stunning, well-managed national parks that offer the same caliber of scenery, minus the crowds.
From remote volcanic islands to hidden desert canyons, these underrated national parks prove you don’t need a reservation system to experience jaw-dropping landscapes, wildlife, and adventure. In fact, in many cases, the solitude only adds to the magic.
Here are 9 of the most overlooked U.S. national parks worth exploring now — before everyone else catches on.
1. North Cascades National Park, Washington
Why It’s Special: Rugged alpine peaks, over 300 glaciers, and almost zero crowds.
Located just three hours from Seattle, North Cascades is one of the least visited national parks in the U.S. — and that’s a mystery. With jagged mountains, turquoise lakes like Diablo and Ross, and a European Alps-like landscape, it’s a hiker’s paradise.
Top Things to Do:
- Hike the Maple Pass Loop for panoramic alpine views
- Take a scenic drive on the North Cascades Highway
- Kayak or canoe on Ross Lake
- Spot wildlife like black bears, marmots, and mountain goats
Insider Tip: Fall offers fiery foliage without the crowds. You’ll feel like you’ve discovered a secret Switzerland.
2. Great Basin National Park, Nevada
Why It’s Special: Star-studded skies, ancient bristlecone pines, and cave tours.
Tucked along Nevada’s eastern border, Great Basin is the opposite of Vegas glitz. This park is where nature goes undisturbed — and it’s one of the darkest sky parks in the country. Combine that with hikes up 13,000-foot Wheeler Peak and guided tours through Lehman Caves, and you’ve got a destination that blends stargazing, solitude, and history.
Top Things to Do:
- Join a Lehman Caves tour (reserve in advance!)
- Camp under Milky Way-filled skies
- Hike the Bristlecone Pine Trail — home to trees over 4,000 years old
- Drive the Wheeler Peak Scenic Drive
Insider Tip: Bring layers — even in summer, the high elevation keeps temperatures crisp.
3. Isle Royale National Park, Michigan
Why It’s Special: Remote island wilderness accessible only by boat or seaplane.
Tucked into Lake Superior, Isle Royale is a true escape. This island park sees fewer visitors in a year than Yellowstone sees in a day. Once you’re there, it’s nothing but pristine forest, hidden coves, and trails that might take hours without seeing another person.
Top Things to Do:
- Backpack the 40-mile Greenstone Ridge Trail
- Take a ranger-led boat tour around the archipelago
- Dive into Lake Superior’s shipwreck history
- Spot moose and wolves in their natural habitat
Insider Tip: The park is only open from mid-April through October. Plan well and disconnect completely.
4. Congaree National Park, South Carolina
Why It’s Special: The largest intact expanse of old-growth bottomland hardwood forest in the U.S.
Congaree is a quiet wonder, often overshadowed by the Blue Ridge Mountains or Charleston’s charm nearby. But inside its swampy, surreal ecosystem lies one of the most biologically rich environments in the Southeast.
Top Things to Do:
- Walk the Boardwalk Loop Trail over swampy waters
- Canoe through the Cedar Creek Canoe Trail
- Visit during synchronous firefly season (late spring — reserve early)
- Birdwatching: expect owls, woodpeckers, and herons galore
Insider Tip: Visit after a rainstorm — the forest becomes a mirror of reflections and rich soundscapes.
5. Guadalupe Mountains National Park, Texas
Why It’s Special: Texas’ highest peak and a stunning fossil reef turned mountain range.
Guadalupe Mountains doesn’t get the same attention as nearby Big Bend, but it should. Home to Guadalupe Peak (the highest in Texas), striking canyons, and fossilized reef formations, this park offers intense hikes and rich geology in an uncrowded setting.
Top Things to Do:
- Summit Guadalupe Peak for sweeping desert views
- Hike into McKittrick Canyon, especially in fall
- Explore Dog Canyon or Devil’s Hall
- Camp at Pine Springs Campground under pristine skies
Insider Tip: Fall is peak time — the canyon forests explode in autumn color, a rarity in the Southwest.
6. Dry Tortugas National Park, Florida
Why It’s Special: Crystal-clear waters, coral reefs, and a Civil War-era fort — 70 miles offshore.
Accessible only by ferry or seaplane from Key West, Dry Tortugas feels like the Caribbean. Centered around Fort Jefferson, it’s a snorkeler’s paradise with coral reefs, shipwrecks, and white sand beaches.
Top Things to Do:
- Snorkel around the moat wall and coral heads
- Camp on Garden Key (permit required, primitive camping only)
- Explore the 19th-century Fort Jefferson
- Birdwatch during spring migration
Insider Tip: Spend the night. Day trippers leave by 3 p.m., and campers get sunset serenity and starlit solitude.

7. Black Canyon of the Gunnison National Park, Colorado
Why It’s Special: A jaw-dropping, steep canyon few have heard of — and even fewer visit.
Often called “the Grand Canyon’s goth cousin,” Black Canyon slices 2,700 feet into Colorado’s crust with sheer cliffs and dramatic shadows. It’s quiet, intense, and one of the most visually stunning places in the Rockies.
Top Things to Do:
- Drive the South Rim Road for epic overlooks

Why It’s Special: Boiling mud pots, steaming fumaroles, and snow-covered peaks.
If you love Yellowstone but hate the crowds, Lassen is your dream come true. Located in Northern California, it boasts all four types of volcanoes, plus hydrothermal activity, wildflower-filled meadows, and stunning alpine lakes.
Top Things to Do:
- Hike the Bumpass Hell Trail to see steaming geothermal wonders
- Summit Lassen Peak — an active volcano
- Paddle or swim in Manzanita Lake
- Snowshoe or cross-country ski in winter months
Insider Tip: It’s one of the few parks where you can see bubbling mud pots without standing in line.
9. Theodore Roosevelt National Park, North Dakota
Why It’s Special: Badlands, bison, and a fascinating presidential backstory.
Named for the president who fell in love with the Dakota wilderness, this park blends rugged badlands with prairie grasslands, rich wildlife, and some of the best sunsets in the Midwest. You’ll see wild horses, bison, and barely another soul.

- Visit Roosevelt’s historic ranch cabin
- Hike the Painted Canyon Trail
- Attend the Medora Musical for Western flair
Insider Tip: Summer evenings here glow with surreal color. Stay late for golden hour photography.
Why These Underrated Parks Matter
With overtourism affecting many of the big-name national parks, these lesser-known gems offer a more sustainable and peaceful way to experience America’s natural beauty. You’ll support local economies, enjoy uninterrupted solitude, and in many cases, get a more personal connection with rangers, landscapes, and wildlife.
Whether you’re into hiking, stargazing, kayaking, or just finding somewhere quiet, these parks deliver all the awe without the chaos.
Tips for Visiting Less-Traveled National Parks
- Plan ahead: Many underrated parks lack in-park lodging or services. Book early.
- Pack for isolation: Bring your own food, water, and emergency supplies.
- Respect Leave No Trace principles: These parks depend on visitor responsibility to stay pristine.
- Engage with rangers: Smaller parks often have passionate local staff who offer deeper stories and insights.
Final Thoughts
Skipping the big-name parks doesn’t mean sacrificing quality. In fact, the opposite is often true: in lesser-known national parks, you can hear your footsteps on the trail, spot wildlife without a telephoto lens, and watch the stars without jostling for a campsite.
If you’re looking for your next epic outdoor adventure — and want it on your own terms — it’s time to look beyond the obvious.
