America’s national park system is pretty impressive, but it’s pretty obvious that there are some glaring omissions. While places like Yellowstone and the Grand Canyon get all the glory, plenty of other stunning locations are stuck with lesser designations or split between different agencies.
These overlooked gems offer the same spectacular scenery, unique ecosystems, and recreational opportunities as their more famous cousins. Some are already partially protected as state parks or national preserves, while others exist in a bureaucratic limbo that doesn’t quite do them justice. Here are ten places that deserve the full national park treatment, complete with that coveted arrowhead logo and the protection that comes with it.
10. Delaware Water Gap, Pennsylvania/New York
The Delaware River didn’t mess around when it decided to carve through the Appalachian Mountains. This dramatic gorge features cliffs that shoot 1,200 feet straight up from the water, creating one of those “how is this even real” moments that make you probably believe in a higher power.
You can paddle the river, hike sections of the Appalachian Trail, or explore Revolutionary War-era villages that somehow survived urban sprawl. Black bears lumber through the forests while bald eagles soar overhead, proving that wilderness can thrive surprisingly close to major metropolitan areas.
9. Assateague Island, Maryland
Wild horses galloping across spotless beaches sounds like something from a fantasy novel, but it’s just another Tuesday on Assateague Island. These aren’t escaped carnival ponies either. They’re the hardy descendants of domestic horses that have been living free for centuries, developing their own social structures and survival instincts.
The horses steal the spotlight, but the island offers much more than equine entertainment. Miles of unspoiled coastline provide excellent surf fishing, while the salt marshes teem with birds. Hello, birdwatching! On clear nights, you’ll get some of the darkest skies on the East Coast, perfect for stargazing without the usual light pollution, so no more playing “star or airplane”.
8. Tallgrass Prairie National Preserve, Kansas
Before settlers arrived with their plows, tallgrass prairie covered an area larger than most countries. Today, finding authentic prairie is like searching for unicorns but unicorns might actually be easier to locate. This Kansas preserve protects one of the last remnants of an ecosystem that once defined the American heartland.
When the wind hits the grass just right, the entire landscape moves like a green ocean. Bison have returned to roam these plains, and prescribed burns keep the ecosystem healthy. It’s humbling to stand in a landscape that hasn’t changed much since Lewis and Clark passed through.
7. Grand Staircase-Escalante, Utah
Utah hoards red rock landscapes like a scenic miser, and the Grand Staircase-Escalante might be its most jealously guarded secret. Slot canyons twist through impossible sandstone formations that truly defy what you might know about physics.
Paleontologists regularly uncover fossils here that rewrite textbooks, while hikers discover hidden waterfalls and ancient petroglyphs. The remote location keeps crowds away, meaning you can still find solitude in some of the most spectacular canyon country in the Southwest. National Park status would be cool, but maybe it’s under cover persona is half of the allure.
6. Hocking Hills State Park, Ohio
Ohio doesn’t usually make anyone’s list of scenic destinations, which makes Hocking Hills feel like discovering a hidden treasure in your basement. Deep gorges, waterfalls, and unique rock formations prove that spectacular scenery isn’t limited to western states.
Old Man’s Cave sounds like a retirement home for hermits, but it’s actually a massive recess cave that’s been wowing visitors for generations. Cedar Falls plunges through a hemlock-lined gorge, while Ash Cave creates a natural amphitheater that puts most concert venues to shame. It ticks all the boxes for an epic outdoor adventure, now it just needs that coveted National Parks designation.
5. White Mountains, New Hampshire/Maine
Mount Washington has killed more people than some active volcanoes, which tells you everything you need to know about the White Mountains’ serious alpine credentials. The weather here is legendarily unpredictable and you can start a hike in shorts and end up in a blizzard by lunch.
The Presidential Range offers above-treeline hiking that’s rare east of the Rockies. Rocky summits provide views across multiple states, while the AMC hut system creates a European-style hiking experience. Fall foliage here is so spectacular it causes actual traffic jams so be sure to put this New England gem on your bucket list.
4. Monument Valley, Arizona
Every Western movie ever made has basically turned Monument Valley into America’s unofficial logo. Those iconic sandstone buttes rising from the desert floor are more recognizable than most actual national parks (or John Wayne), yet the area remains under tribal management rather than federal protection.
Navajo guides lead tours through this sacred landscape, sharing stories that go far deeper than geology. The massive red rock formations create an almost alien environment, especially during sunrise and sunset when the rocks seem to glow from within.
3. Porcupine Mountains, Michigan
The Porkies escaped the logging boom that turned most of the Great Lakes region into stumps, preserving the largest tract of old-growth hardwood forest in the Midwest. These ancient trees are living witnesses to what the region looked like before European settlement.
Massive hemlocks and maples create cathedral-like groves, while crystal clear lakes reflect the surrounding wilderness. The park’s rustic cabins let you sleep surrounded by centuries-old trees, and the Lake Superior shoreline adds dramatic cliffs and hidden beaches to the mix.
2. Niagara Falls, New York
The fact that one of the world’s most famous waterfalls isn’t a national park feels like a cosmic oversight. While millions of tourists flock to the American side, they’re experiencing a patchwork of state parks and tourist traps rather than a cohesive national park experience.
The falls themselves remain genuinely spectacular despite the surrounding commercialization. When you’re standing next to that thundering wall of water, feeling the mist on your face and the ground vibrating beneath your feet, all the tourist kitsch fades away. National park status would elevate the American experience to match the falls’ international reputation and make it the truly world class attraction it was meant to be.
1. Custer State Park, South Dakota
Custer State Park already acts like a national park, complete with entrance fees, visitor centers, and some of the best wildlife viewing in North America. The park’s free-roaming bison herd creates traffic jams that would make city commuters jealous, while the scenic drives rival anything in the national park system.
The Wildlife Loop Road guarantees bison sightings, prairie dog towns, and possibly the worst case of wildlife-induced road rage you’ll ever experience. The Needles Highway threads between granite spires with tunnels so narrow that RV drivers have been known to abandon their vehicles and hitchhike home. The area already meets every criterion for national park status; it’s just waiting for Congress to make it official.
