America’s national parks are a national treasure — one of the genuinely great achievements of American public policy, dating to Yellowstone’s establishment in 1872. The land preserved in these parks represents some of the most spectacular landscape on Earth, and the fact that it belongs to every American equally, preserved in perpetuity from private development, is something to be proud of.
But the park system’s most famous names have become victims of their own popularity. Yosemite Valley in July is a traffic jam surrounded by magnificent scenery. The South Rim of the Grand Canyon during peak season is a crowd management challenge. Zion’s Angels Landing requires lottery permits and still has hikers queuing for hours on chains during peak periods. Arches has implemented timed entry systems to manage visitor volume.
The good news is that most of the park system’s 63 national parks and hundreds of affiliated monuments, recreation areas, and historic sites are not like this. Magnificent, under-visited, and offering experiences that rival the famous parks — here are the parks that deserve a spot on your list.
Great Basin National Park, Nevada
Great Basin is the second-least-visited national park in the lower 48, and it is bewilderingly good. Located in eastern Nevada near the Utah border, in one of the most genuinely remote parts of the contiguous United States, it receives fewer than 150,000 visitors annually — compared to Zion’s 5 million or Yosemite’s 4 million.
What you get for making the drive: Wheeler Peak rising to 13,063 feet, the only significant glacier in the Great Basin, ancient bristlecone pine trees (the oldest living organisms on Earth — individual trees in Great Basin are over 5,000 years old), Lehman Caves with some of the most elaborate cave formations in the national park system, and some of the darkest skies in the lower 48.
The Great Basin is high desert — daytime temperatures in summer are manageable, nights are cold, and the air is extraordinarily clear. The stars are incomparable. Come in late summer or early fall, plan to stay at least two nights, and bring layers.
Congaree National Park, South Carolina
Congaree protects the largest remaining tract of old-growth bottomland hardwood forest in the southeastern United States. It’s a designated International Biosphere Reserve and International Dark Sky Park, receives fewer than 200,000 visitors annually, and is genuinely remarkable.
The experience is nothing like what most people expect from a national park. There are no mountains, no dramatic vistas. Instead: ancient trees, some of the tallest in the eastern United States, rising from a floodplain forest floor. Fireflies synchronize their flashing in early June in a phenomenon so extraordinary that the park runs ranger-led programs around it. Alligators. River otters. Ancient bald cypress trees standing in still water.
Congaree is hot and humid in summer (it is South Carolina lowcountry), so spring and fall are optimal. The boardwalk trail is accessible and gives you the forest floor experience without significant elevation. Camping in Congaree, falling asleep in an old-growth forest with no light pollution, is an experience that doesn’t appear in the magazines but is unforgettable.
Isle Royale National Park, Michigan
Isle Royale is an island national park in Lake Superior, accessible only by boat or seaplane from Houghton or Copper Harbor, Michigan, or Grand Portage, Minnesota. The logistics barrier keeps crowds low: it’s the least-visited national park in the contiguous United States by visitation, receiving around 25,000 visitors annually.
What you get for making the effort: one of the great wilderness experiences in the eastern U.S. The island is 45 miles long and 9 miles wide, with 165 miles of trails, pristine inland lakes accessible by canoe and kayak, and one of the most studied wolf-moose ecosystems on Earth.
Isle Royale requires planning. There are no roads — you hike between campgrounds or paddle. Supplies must come in on the ferry. Weather on Lake Superior can be severe. But the island is genuinely wild in a way that few places in the eastern U.S. remain, and the experience of multi-day backcountry travel here is memorable.
Guadalupe Mountains National Park, Texas
Guadalupe Mountains sits in far west Texas along the New Mexico border and contains the highest peak in Texas (Guadalupe Peak, 8,751 feet), an extraordinary fossil reef from an ancient Permian sea, and one of the finest fall color displays in Texas — a surprise achievement for a desert park.
The park receives around 200,000 visitors annually and has no maintained roads into its interior — it’s a hiking and backpacking park. The trails are challenging and rewarding. The geology is world-class for anyone interested in paleontology or geology (the Capitan Reef formation is one of the best-exposed fossil reef systems in the world). The dark skies are excellent.
Guadalupe Mountains pairs beautifully with nearby Carlsbad Caverns National Park in New Mexico (itself a stunning, also underrated destination), making a multi-day trip through this corner of the Chihuahuan Desert highly worthwhile.
Voyageurs National Park, Minnesota
Voyageurs is a water-based national park in northern Minnesota near the Canadian border, centered on a network of interconnected lakes. There are no roads within the park’s interior — everything is accessed by boat. This means most visitors either rent a houseboat or bring their own. And this means most people skip it entirely.
The people who make the trip are rewarded with one of the most genuinely remote experiences available in the eastern U.S.: miles of undeveloped shoreline, excellent fishing, wildlife that includes black bears, wolves, moose, bald eagles, and loons, and the extraordinary northern Minnesota night sky.
Houseboating in Voyageurs — renting one of the outfitter houseboats that operate on the park’s lakes, spending several days moving between islands, fishing, swimming in water clear enough to see 20 feet down — is one of the great underrated American vacation experiences.
North Cascades National Park, Washington
The Pacific Northwest gets significant attention for Olympic National Park (deservedly) and Mount Rainier (also deservedly). North Cascades, which flanks both sides of its eponymous mountain range north of Seattle, receives far less — despite being one of the most spectacular mountain landscapes in the lower 48.
The Cascades in this range are genuinely alpine: more than 300 glaciers, jagged granite peaks, turquoise-green glacially-fed lakes, and forests that receive extraordinary snowfall in winter. The Cascade Pass trail and the overnight circuit to Sahale Arm are among the finest mountain hikes in the Pacific Northwest. The North Cascades Highway (SR-20), closed in winter, is one of the great scenic drives in America.
If you’re traveling to the Seattle area and have additional days, the drive to North Cascades and even a single overnight at a backcountry camp in the park is more memorable than many far more famous destinations.
Black Canyon of the Gunnison National Park, Colorado
Colorado is well-stocked with famous outdoor destinations — Rocky Mountain National Park, Mesa Verde, Great Sand Dunes. Black Canyon of the Gunnison receives fewer visitors than any of them, despite being one of the most dramatic geological formations in the American West.
The canyon is narrow, deep, and steep in ways that photographs don’t fully convey. The Gunnison River has carved a gorge 48 miles long and up to 2,722 feet deep through some of the oldest exposed rock in North America — Precambrian gneiss and schite that is nearly 2 billion years old. The walls are so steep and narrow that some sections receive less than 30 minutes of direct sunlight per day.
The south rim road offers a series of overlooks that are consistently stunning. The hiking into the inner gorge is serious — steep, unmarked, and requiring route-finding — and is one of the more adventurous experiences available in the national park system.
Plan a Less-Famous Trip
The pressure to see the famous parks is understandable — they’re famous for a reason. But the experience of a crowded Yosemite with hour-long queues at the valley floor shuttle stop is genuinely diminished from what the park offers in solitude.
The alternative — planning a trip to a park you’ve never heard of, arriving with lower expectations, and discovering something magnificent that you effectively have to yourself — is one of travel’s better surprises. The National Park Service maintains detailed information for every park in the system. Start with the least-visited parks in your region and see what they offer.
The parks are yours. Use all of them.
