Top 10 US National Parks for Hiking
America has 63 national parks, and nearly all of them have their fair share of hiking trails. But hiking quality varies enormously. We ranked the top ten parks on the depth and variety of their trail systems, the quality of the scenery on foot (not just from a car window or overlook), the accessibility of the backcountry, and that hard-to-define quality of a trail that earns its difficulty — where the effort and the payoff feel honestly matched. From the granite cathedrals of the Sierra Nevada to the rainforest-to-glacier range of the Olympic Peninsula to a quiet corner of the North Cascades that most Americans have never visited, these are the parks where hiking isn’t an amenity. It’s the point.
1. Yosemite National Park — California, Sierra Nevada
No park on earth packages granite, waterfalls, and high alpine terrain into a single valley the way Yosemite does. Trails span everything from stroller-accessible valley floors to knife-ridge summit scrambles, and the sheer drama of the scenery — Half Dome’s north face looming above you, Yosemite Falls audible from miles away — is unmatched. With over 800 miles of maintained trail across wildly varied ecosystems, it earns the top spot on hiker density, trail quality, and iconic payoff.
Signature hikes: Half Dome via cables, the Mist Trail to Nevada Fall, Cathedral Lakes, Clouds Rest, Sentinel Dome.
2. Grand Teton National Park — Wyoming, Northern Rockies
The Tetons rise so abruptly from the valley floor that almost every hike starts with a jaw-drop. Unlike Yellowstone next door, Grand Teton is entirely about the mountains — and the trails deliver immediately, gaining thousands of feet into cirques filled with turquoise lakes and wildflower meadows. The scenery-to-effort ratio here is as good as anywhere in the country, and the absence of Yellowstone’s crowds makes the backcountry feel genuinely wild.
Signature hikes: Cascade Canyon to Lake Solitude, Paintbrush Canyon Loop, Amphitheater & Surprise Lakes, Delta Lake, Death Canyon Shelf.
3. Rocky Mountain National Park — Colorado, Front Range
With 60 named peaks above 12,000 feet and Trail Ridge Road cresting 12,183 feet before you even lace up, RMNP is the closest thing America has to dedicated alpine hiking outside Alaska. The park excels at tundra traverses, high-lake day hikes, and summit approaches that reward ambitious hikers without requiring technical mountaineering skills. Early summer snowfields and bighorn sheep around nearly every bend add to the experience.
Signature hikes: Longs Peak via the Keyhole Route, Sky Pond, Flattop Mountain & Hallett Peak, Chasm Lake, Emerald Lake Trail, Dream Lake.
4. Olympic National Park — Washington, Olympic Peninsula
Olympic is three parks in one: temperate rainforest, glaciated alpine peaks, and 73 miles of wild Pacific coastline. That ecological range means the hiking is unlike anywhere else in the country — you can walk through moss-draped old-growth Sitka spruce in the morning and gain a glacial ridge by afternoon. The isolation of the peninsula keeps crowds manageable and the wilderness feeling authentic, even on popular trails.
Signature hikes: Hoh River Trail, Seven Lakes Basin Loop, Hurricane Hill, Ozette Triangle coastal loop, Mount Storm King.
5. Glacier National Park — Montana, Northern Rockies
Going-to-the-Sun Road is famous, but Glacier’s trails are the real attraction. The park sits on a continental divide of absurd geological drama — hanging valleys, turquoise lakes, and rugged peaks on a scale that dwarfs most Rocky Mountain parks. Grizzly encounters are a genuine possibility, and the wildflower displays in July rival anything in the alpine west. Hike here before the glaciers that gave it its name are gone entirely.
Signature hikes: Highline Trail, Grinnell Glacier, Iceberg Lake, Ptarmigan Tunnel, Avalanche Lake.
6. Great Smoky Mountains National Park — Tennessee/North Carolina, Southern Appalachians
The most visited national park in the country earns its reputation among hikers too — 800 miles of trails cross ancient, biodiverse hardwood forest with more tree species than all of Northern Europe. The Smokies peak in spring wildflower season and fall foliage, and the Appalachian Trail ridge walk from Fontana Dam to Davenport Gap is some of the finest hiking on the entire 2,190-mile route. Free admission and no permit required for most trails keeps it accessible to everyone.
Signature hikes: Alum Cave to Mount LeConte, Andrews Bald via Forney Ridge, Charlies Bunion, Laurel Falls, Chimney Tops.
7. Zion National Park — Utah, Colorado Plateau
Zion’s narrow sandstone canyon walls rising 2,000 feet above the Virgin River create a hiking experience that’s entirely its own category. The Angel’s Landing chain scramble and the slot canyon wade of The Narrows are two of the most recognizable hiking experiences in the world — and the less-famous backcountry beyond the main canyon is even better. The trade-off is steep crowds in peak season; spring and fall visits are essential.
Signature hikes: Angel’s Landing, The Narrows (bottom-up), Observation Point, The Subway, Canyon Overlook Trail.
8. Acadia National Park — Maine, Downeast Coast
Acadia is one of the best hiking parks east of the Rockies — compact, dramatically scenic, and threaded with stone-step carriage roads and iron-rung ladder trails that make it genuinely unique. The Beehive and the Precipice offer exposure and scrambling that feel far more serious than the modest elevations suggest. The combination of Atlantic ocean views, granite summits, and intact Acadian spruce-fir forest is irreproducible anywhere else on the East Coast.
Signature hikes: The Precipice Trail, Beehive Loop, Acadia Mountain, Jordan Pond & North Bubble, Ocean Path.
9. Yellowstone National Park — Wyoming/Montana/Idaho, Greater Yellowstone
Yellowstone’s ranking reflects honest reality: it’s one of the world’s great natural wonders, but its hiking is secondary to its geothermal spectacle and the abundant wildlife. Away from the thermal basins, the backcountry opens into genuine wildlands — the Bechler River corridor, the Black Canyon of the Yellowstone, and Mount Washburn all deliver excellent hiking. But you go to Yellowstone for the geysers, the bison, and the wolves. The hiking is a bonus.
Signature hikes: Mount Washburn via Dunraven Pass, Fairy Falls & Grand Prismatic Overlook, Black Canyon of the Yellowstone, Heart Lake backcountry, Shoshone Lake via DeLacy Creek.
10. North Cascades National Park — Washington, Cascade Range
America’s least-visited major mountain park is also one of its most spectacular — and its low profile is exactly what makes it great for hiking. Over 300 glaciers drape jagged volcanic peaks above valleys filled with old-growth Douglas fir, and the trails are genuinely remote. Permits are easy to get, wildlife is abundant, and the scenery along routes like Maple Pass and Sahale Arm competes with anything in the Rockies.
Signature hikes: Maple Pass Loop, Sahale Arm & Cascade Pass, Chain Lakes Loop, Blue Lake, Diablo Lake Trail.
