National parks represent some of America’s most spectacular natural treasures, but visiting them doesn’t always have to empty your wallet. While many famous parks like Yellowstone and Grand Canyon charge entrance fees that can reach $35 per vehicle, plenty of equally stunning destinations welcome visitors without asking for a penny at the gate.
These free parks offer everything from ancient forests and pristine coastlines to dramatic mountain ranges and underground cave systems. The beauty of these no-fee parks is that they remove one barrier to outdoor adventure, making nature accessible to families on tight budgets and spontaneous travelers alike.
Here is a list of 20 national parks across the United States where you can experience America’s natural wonders without paying an entrance fee.
Biscayne National Park, Florida
Located just south of Miami, Biscayne National Park protects a unique underwater world where 95% of the park lies beneath the surface. The park encompasses coral reefs, mangrove forests, and crystal-clear waters that make it a snorkeler’s paradise.
You can explore the visitor center on the mainland for free, though boat tours and equipment rentals will cost extra if you want to venture out to the islands.
Channel Islands National Park, California
Often called ‘California’s Galapagos,’ Channel Islands National Park sits about 20 miles off the coast near Ventura. The park itself doesn’t charge admission, but you’ll need to book a ferry ride to reach the islands, which can cost around $60 per adult.
Once there, you can hike rugged trails, explore sea caves, and spot wildlife like island foxes that exist nowhere else on Earth.

Gateway Arch National Park, Missouri
America’s smallest national park centers around the iconic 630-foot Gateway Arch in downtown St. Louis. The park celebrates St. Louis’ role as the “Gateway to the West” during the era of westward expansion.
While the park grounds are free to explore, riding the tram to the top of the arch costs about $15 per adult and offers stunning views of the Mississippi River and city skyline.
Glacier Bay National Park, Alaska
This pristine wilderness in southeast Alaska showcases the power of glaciers on a massive scale, with over 1,000 glaciers carving through mountains and into the sea. Most visitors arrive by cruise ship or chartered boat from nearby Juneau, as there are no roads into the park.
The experience of watching house-sized chunks of ice crash into the ocean—phenomenon known as calving—creates memories that last a lifetime.
Great Basin National Park, Nevada
Hidden in eastern Nevada’s high desert, Great Basin National Park offers an incredible diversity of landscapes from 5,000-foot valleys to 13,000-foot peaks. The park is home to ancient bristlecone pine trees, some over 4,000 years old, making them among the oldest living things on Earth.

Wildlife enthusiasts come here to spot orcas, humpback whales, sea otters, and thousands of seabirds that nest on coastal cliffs.
Lake Clark National Park, Alaska
Often overshadowed by more famous Alaska parks, Lake Clark protects a stunning combination of turquoise lakes, active volcanoes, and pristine wilderness across 4 million acres. The park sits across Cook Inlet from Anchorage but feels worlds away, accessible only by small plane from the city.

America’s newest national park, designated in 2020, New River Gorge protects 70,000 acres of rugged Appalachian landscape carved by one of the oldest rivers in North America. The gorge offers world-class rock climbing, whitewater rafting, and hiking, with the iconic New River Gorge Bridge serving as a dramatic backdrop.
Fall brings spectacular foliage that transforms the gorge into a canvas of brilliant colors visible from numerous overlooks.
North Cascades National Park, Washington
Called the ‘American Alps’ for its jagged peaks and pristine alpine lakes, North Cascades National Park protects over 300 glaciers and some of the most dramatic mountain scenery in the lower 48 states.

Voyageurs National Park, Minnesota
This water-based park along the Minnesota-Canada border protects a landscape of interconnected lakes, islands, and forests that once served as highways for French-Canadian voyageurs. Over 200,000 acres of wilderness can only be explored by boat, canoe, or kayak, making it a paddler’s paradise.
In winter, the frozen lakes become a highway for snowmobiles, cross-country skiers, and ice fishermen seeking northern pike and walleye.
Wind Cave National Park, South Dakota
Beneath the rolling prairie of the Black Hills lies one of the world’s longest and most complex cave systems, known for its unique calcite formations called boxwork. Above ground, the park protects 33,000 acres of mixed-grass prairie where bison, elk, and prairie dogs roam freely in one of the few remaining intact grassland ecosystems.
The contrast between the underground maze and the open prairie creates a unique dual experience.
Wrangell-St. Elias National Park, Alaska
At 13.2 million acres, Wrangell-St. Elias is America’s largest national park—bigger than Yellowstone, Everglades, and Grand Canyon combined. This massive wilderness contains the continent’s largest collection of peaks over 16,000 feet, including Mount St. Elias, North America’s second-highest coastal mountain.
The park’s two rough gravel roads provide access to historic mining sites and spectacular mountain views. Still, much of this incredible landscape remains as wild and untouched as when the first explorers arrived.
