Ten Free-Entry National Parks You Can Visit All Year Long
Biscayne National Park, Florida
Biscayne National Park, Florida, is a rare national park where nearly 95 percent of its beauty lies beneath the sea’s surface. Stretching from the vibrant waters of Biscayne Bay to the open Atlantic, the park protects living coral reefs, shipwreck trails, and dense mangrove forests that act as nurseries for marine life. Visitors can snorkel over coral gardens, kayak through quiet mangrove tunnels, or take a boat tour to remote islands where dolphins and sea turtles often appear. Unlike Florida’s busy beaches, Biscayne offers a calm, untouched tropical escape where nature rules and the ocean feels endless.
Channel Islands National Park, California
Channel Islands National Park, California, feels like a journey to a forgotten corner of the Pacific. Located just off the Southern California coast, this collection of five rugged islands is home to wildlife found nowhere else on Earth, from tiny island foxes to rare seabirds nesting on dramatic cliffs. Sea caves carve through towering rock formations, and crystal-clear waters invite kayaking and snorkeling. Because access is only by boat or small aircraft, the islands remain uncrowded and wonderfully wild, offering visitors the rare feeling of discovering a place barely touched by modern life.
Congaree National Park in South Carolina
Congaree National Park in South Carolina preserves a lush floodplain forest that feels almost prehistoric. Some of the tallest trees in eastern North America rise from its swampy ground, creating cathedral-like spaces beneath their branches. Elevated boardwalks allow visitors to wander safely through this wetland world, where owls, deer, and fireflies thrive. In the early morning or just before dusk, mist floats between the trees, and the forest glows with golden light, making Congaree one of the most peaceful and photogenic parks in the country.
Cuyahoga Valley National Park, Ohio
Cuyahoga Valley National Park, Ohio, is a refreshing blend of wilderness and history tucked between Cleveland and Akron. Forested trails wind past waterfalls, rolling meadows, and riverbanks where wildlife quietly flourishes. At the same time, remnants of old canals, bridges, and railroads tell the story of America’s industrial past. Visitors can hike through scenic valleys, cycle along the Towpath Trail, or even ride a vintage train through the park, making Cuyahoga a destination where nature and culture meet beautifully.
Gates of the Arctic National Park in Alaska
Gates of the Arctic National Park in Alaska is the definition of true wilderness. There are no roads, no marked trails, and no visitor centers—only vast tundra, rugged mountains, and broad rivers flowing through untouched land.10This is one of the few places left on Earth where you can experience nature exactly as it has existed for thousands of years. Caribou migrate across the plains, wolves roam freely, and the northern sky glows with endless daylight in summer and shimmering auroras in winter, making every visit feel like a once-in-a-lifetime adventure.
Gateway Arch National Park in Missouri
Gateway Arch National Park in Missouri may be compact, but it holds immense historical and symbolic significance. Centered around the iconic 630-foot Gateway Arch in St. Louis, the park celebrates America’s westward expansion and the pioneering spirit that shaped the nation. Visitors can ride a tram to the top of the arch for sweeping views of the Mississippi River and city skyline, then explore museums and riverside paths that connect history with modern urban life. It is a unique national park where culture, architecture, and storytelling take center stage.
Glacier Bay National Park, Alaska
Glacier Bay National Park, Alaska, is a place where ice and ocean collide in breathtaking ways. Massive glaciers slowly carve their way through mountains before crashing into deep blue fjords, sending thunderous waves across the water. Whales, sea otters, and seals thrive in these cold, nutrient-rich waters, often appearing alongside boats that explore the bay. Every turn reveals towering ice cliffs and snow-covered peaks, making Glacier Bay one of the most visually dramatic and awe-inspiring national parks on the planet.
Great Basin National Park in Nevada
Great Basin National Park in Nevada is a hidden gem where desert landscapes rise into snow-capped mountains. The park is home to some of the world’s oldest trees, ancient bristlecone pines that have survived for thousands of years in the thin mountain air. Beneath the surface, limestone caves reveal shimmering formations carved by water over centuries. At night, the park becomes one of the darkest places in the United States, offering brilliant views of the Milky Way and turning every visit into a stargazer’s dream.
The Great Smoky Mountains National Park
The Great Smoky Mountains National Park, in North Carolina and Tennessee, draws millions of visitors each year because of its unmatched beauty and diversity. Rolling ridges wrapped in mist, rushing mountain streams, and valleys filled with wildflowers create a landscape that changes with every season.

Whether you’re hiking to waterfalls or simply driving through the mountain passes, the Smokies never fail to leave a lasting impression.
