From Alaska’s remote bush to downtown Cleveland, our national parks provide us with millions of acres of public land to explore. We compiled a list of the best hikes in each park, according to the wilderness guides, park rangers, and hikers who know them.

Acadia

Maine

The Expert: Pat Johnson, Maine Outdoor Adventure Club trip leader

The Hike: Penobscot and Sargent Mountain Loop

Summit two of the park’s highest peaks on this 9.5-mile loop through thick spruce forest that eventually gives way to pink-tinted granite crags. The route offers access to three carriage-road bridges, relics from John D. Rockefeller Jr.’s philanthropic work—consider detouring less than a half mile to the 230-foot-long Cliffside Bridge.

Arches

Utah

The Expert: John Tillison, former Washington State park ranger

The Hike: Devils Garden Loop

You’ll see eight of the park’s stunning rock formations on this 7.9-mile tour through Devils Garden. It’s an easy stroll to the longest arch in North America, Landscape Arch, but then the gentle trail transitions to narrow ledges that involve some scrambling to reach Double O, Navajo, and Partition Arches.

Badlands

South Dakota

The Expert: Kelsy Koerlin, Rapid City, South Dakota, hiker

The Hike: Notch Trail

An easy 1.5-mile round-trip, this trail tours the best of the Badlands’ otherworldly assortment of eroded rock and clay, splashed with a brilliant array of red, white, and black. Ascend a log ladder to a bird’s-eye view of the rugged terrain and distant prairie of White River Valley.

Big Bend

Texas

The Expert: Courtney Lyons-Garcia, Big Bend Conservancy executive director

The Hike: Lost Mine Trail

Soak in the solitude through the heart of the Chisos Mountains for 4.8 miles round-trip, past alligator junipers and piñon pines. The views of the Sierra del Carmen mountains in Mexico are spectacular. Visit in November or March to avoid the summer heat.

Biscayne

Florida

The Expert: Sandra Friend, author of 'The Florida Trail Guide'

The Hike: Spite Highway Trail

Only accessible by boat, Elliot Key is the largest island in the park, home to the “Spite Highway,” a seven-mile sliver of forest that in the 1960s was flattened in opposition to a national-monument designation. It’s the park’s only hiking trail, and on it you’ll be immersed in tropical forests, even as Miami looms to the north.

Black Canyon of the Gunnison

Colorado

The Expert: Elaine Brett, North Fork Valley, Colorado, hiker

The Hike: North Vista Trail

At Exclamation Point, snag the best view of the park’s namesake canyon from 900 feet above the rim. Continue to Green Mountain for a panoramic vista of the San Juan Mountains and Grand Mesa, a seven-mile round-trip.

Bryce Canyon

Utah

The Expert: Charlie Neumann, owner of Willow Canyon Outdoor, in Kanab, Utah

The Hike: Under the Rim Trail

At 23 miles one-way, Under the Rim Trail is the longest in Bryce. Take two days to experience the best of the Paunsaugant Plateau’s hoodoo rock spires. Tackle most of the 5,000 feet in elevation change early by starting at Rainbow Point—you can arrange a shuttle there with the Park Service, free with your entry fee.

Canyonlands

Utah

The Expert: Cort Wright, Moab Adventure Center guide

The Hike: Grand View Point

Although only a two-mile round-trip, the trail leading to Grand View Point isn’t short on views—you’ll gawk at the maze of basins, dozens of canyons, and the La Sal Mountains in the distance. Arrive before dawn (and the crowds) to watch the sun cast the desert in an amber hue.

Capitol Reef

Utah

The Expert: Andrew Wojtanik, former Capitol Reef interpretive ranger

The Hike: Halls Creek Narrows

The beauty of the Halls Creek Narrows, a slot canyon with towering cliffs, is often compared to the famous Narrows of Zion, yet this 22.4-mile round-trip hike is much more remote and rugged. The unmarked route requires a topographic map and compass to navigate. Plan to spend two nights in the backcountry and to get wet through several creek crossings.

Carlsbad Caverns

New Mexico

The Expert: Colin Walfield, Carlsbad Caverns National Park, employee

The Hike: Big Room Trail

It takes about an hour and a half to encircle the Big Room—the largest chamber within Carlsbad Caverns and the largest single cave chamber by volume in North America. This 1.25-mile walk twists among giant stalagmites on a paved trail with handrails. A ranger-guided tour provides insight into the geologic history of the cave system.

Channel Islands

California

The Expert: David Begun, Channel Islands park ranger

The Hike: Lobo Canyon Trail

This 5.2-mile loop is marked by its ecological diversity—more than a dozen rare plants grow in the park. You’ll start in grassland bluffs, with sweeping views of the Pacific, before dropping into a canyon harboring native plants like the canyon sunflower. When you reach the coastline, look out for peregrine falcons and bald eagles.

Congaree

South Carolina

The Expert: Barbie Smrekar, Columbia Outdoor Adventure Network organizer

The Hike: River Trail

Tour this park’s namesake river on a 10.4-mile trail through bottomland and bald cypress forest, home to whitetail deer, otters, and feral hogs. In periods of low water, lounge near the river on exposed sandbars—but keep an eye out for alligators.

Crater Lake

Oregon

The Expert: Erik Fernandez, Oregon Wild wilderness-program manager

The Hike: Garfield Peak Trail

Starting from the Crater Lake Lodge, at an elevation of about 7,000 feet, climb another thousand feet in 1.7 miles to Garfield Peak. From here you’ll have a view of the lake’s crystal-blue water, the deepest in the country at almost 2,000 feet. Go in July for peak wildflower viewing and early in the morning to miss the crowds.

Cuyahoga Valley

Ohio

The Expert: Erik Baldwin, Cleveland Hiking Club member

The Hike: Buckeye Trail

You’ll be hard-pressed to find another park quite like Cuyahoga Valley, nestled in the middle of Cleveland. This one’s for the trail runners and the hardcore hikers: a 12.6-mile section of the statewide 1,400-mile Buckeye Trail from Station Road Bridge to the historic village of Boston. Pass waterfalls and old homesteads dotting densely forested hills before looping back.

Death Valley

California and Nevada

The Expert: Alan Gegax, VegasHikers trip organizer

The Hike: Panamint City Ghost Town

Panamint City was a mining town founded by outlaws in 1873 that quickly garnered a rough reputation, but it was leveled a few years later in a flash flood. Hike to its ruins from Chris Wicht’s Camp, five miles via Surprise Canyon, and admire its flowing water and lush vegetation—rarities in Death Valley.

Denali

Alaska

The Expert: Amy Eckert, travel writer

The Hike: Savage Alpine Trail

Few trails exist in Denali National Park, but among the handful that do, Savage Alpine offers a lot in only eight miles round-trip. Wind over tundra and past Dall sheep before climbing a ridge that on a clear day offers a view of 20,310-foot Denali, North America’s highest peak.

Dry Tortugas

Florida

The Expert: Sandra Friend, author of 'The Florida Trail Guide'

The Hike: Fort Jefferson Loop

You won’t find any wilderness hiking trails in Dry Tortugas, an island 70 miles west of Key West. The main attraction here is Fort Jefferson, the largest masonry structure in the Western Hemisphere. A half-mile loop around the island is a great tour of the fort and overlooks the Caribbean’s crystal waters.

Everglades

Florida

The Expert: Sandra Friend, author of 'The Florida Trail Guide'

The Hike: Snake Bight Trail

The Everglades are better known for swampy boat tours than hiking. But the best trail here is Snake Bight, 1.6 miles one-way through tropical forests. The terminus is a boardwalk that offers bird-watching near a bay—look for pink flamingos.

Gates of the Arctic

Alaska

The Expert: Carl Donohue, Expeditions Alaska guide

The Hike: Koyukuk River Route

Take a plane to a gravel bar on the North Fork of the Koyukuk River, which snakes for more than 100 miles between glacial valleys. Spend a week and follow three creeks—Kachwona, Wolf, and Fish—up to 40 miles deep into the backcountry of the Brooks Range.

Gateway Arch

Missouri

At just 91 acres, Gateway Arch is the smallest National Park. There's not really any hiking, per se, but you should stroll the Mississippi River waterfront and then take the elevator to the top of the Arch.

Glacier

Montana

The Expert: Grete Gansauer, Montana Wilderness Association northwest Montana field director

The Hike: Hidden Lake Trail

Hikers habitually gawk at bears and bighorn sheep along this alpine 5.4-mile out-and-back. In summer you’ll be surrounded by wildflowers as you gaze at Glacier’s jagged peaks. Descend to Hidden Lake via switchbacks to lounge on the beach, with Bearhat and Reynolds Mountains just over your shoulder.

Glacier Bay

Alaska

The Expert: Adam DiPietro, former Glacier Bay trail-crew member

The Hike: Gustavus Plane-Crash Site

This park is celebrated for whale-watching and towering glaciers, and those are definitely must-do’s, but so is this half-mile hike to a Douglas C-47 crash site—in 1957, the crew went down after clipping a tall tree. The trail takes you through woods smattered with mosses, like old man’s beard, and you’ll likely have it to yourself.

Grand Canyon

Arizona

The Expert: Melanie Radzicki McManus, Arizona Trail thru-hiker

The Hike: South Kaibab and Bright Angel Trails

The best hike in the Grand Canyon combines two trails, which traverse the mile-deep canyon, and takes two days. From the South Kaibab Trailhead, descend seven miles via ridges and spend the night next to the Colorado River at the Bright Angel Campground. The next day, huff back up the canyon on the Bright Angel Trail for 9.5 miles.

Grand Teton

Wyoming

The Expert: Amy Eckert, travel writer

The Hike: Lake Solitude

From Jenny Lake, follow the crowds to Inspiration Point, which offers views of the Gros Ventre Mountains. As you enter Cascade Canyon, the masses dwindle as the Tetons’ jagged peaks flank the trail. Pass berry patches and boulder fields before reaching Lake Solitude at mile ten for a secluded night in the backcountry, then trek back the next day.

Great Basin

Nevada

The Expert: Nichole Andler, Great Basin National Park chief of interpretation

The Hike: Timber Creek–Baker Creek Loop Trail

You’ll have this 5.1-mile trail to yourself virtually any time of year, starting from 8,000 feet and walking uphill via Timber Creek, with expansive views of Snake Valley below. Climb another 1,600 feet or so to aspen groves and a meadow, with 11,926-foot Pyramid Peak just overhead.

Great Sand Dunes

Colorado

The Expert: Ryan Kempfer, Salida Mountain Sports employee

The Hike: Sand Ramp Trail

Much more than sand dunes, this hike includes creek crossings, wildlife viewing, and stunning shots of the Sangre de Cristo Mountains. Skirt the eastern edge of the dunes across undulating terrain for 11 miles one-way. Camp near Sand Creek’s cottonwoods before backtracking the next day.

Great Smoky Mountains

North Carolina and Tennessee

The Expert: Diane Petrilla, Smoky Mountains Hiking Club vice president

The Hike: Ramsey Cascades Trail

This patch of woods in the Smokies was never logged, so it’s full of giant trees—some tulip poplars reach seven feet in diameter. Through a jungle of rhododendrons, you’ll ascend more than 2,000 feet over four miles to the tallest waterfall in the park, 100-foot Ramsey Cascades.

Guadalupe Mountains

Texas

The Expert: Cameron Hall, North Texas hiker

The Hike: McKittrick Canyon Trail

McKittrick Canyon is often hailed as the most beautiful spot in Texas. It’s secluded, and in the fall, foliage bursts red and yellow. This 14.8-mile out-and-back takes you to Pratt Cabin and then to a small cave with stalagmites. You’ll ascend McKittrick Ridge on the steepest section of trail in the park, looking down on the canyon.

Haleakala

Hawaii

The Expert: Joani Morris, Friends of Haleakala National Park hike leader

The Hike: Sliding Sands Trail

Towering over Maui at 10,023 feet above sea level, the dormant Haleakala volcano resembles the surface of Mars. For a tour of the caldron, start at the Keoneheehee Trailhead, trekking across the crater’s floor. People flock to the summit to witness a spectacular sunrise (reservations are needed).

Hawaii Volcanoes

Hawaii

The Expert: Barnard Griggs, member of the Hawaiian Trail and Mountain Corp. board of directors

Hot Springs

Arkansas

The Expert: Don Jackson, owner of Ouachita Outdoor Outfitters

The Hike: West Mountain–Mountain Top Trails

Indiana Dunes

Indiana

The Expert: Jean-Pierre Anderson, Indiana Dunes National Park ranger

Isle Royale

Michigan

The Expert: Amy Eckert, Greenstone Ridge Trail thru-hiker

The Hike: Greenstone Ridge Trail

Isle Royale can only be reached by boat, guaranteeing solitude on this remote 42-mile trail that spans the island. You’ll be immersed in boreal forest home to moose and wolves, occasionally topping a bald ridge offering views of the island and Lake Superior.

Joshua Tree

California

The Expert: Tim Liddell, Hi-Desert Hiking Club trip leader

The Hike: Maze Loop

Combine the Maze, North View, and Window Trails for an eight-mile walk through mature desert vegetation like California juniper, yucca, and the park’s namesake Joshua trees. While trail signage has improved in recent years, navigation can still be difficult, so carry a map.

Katmai

Alaska

The Expert: Dan Oberlatz, Alaska Alpine Adventures owner and guide

The Hike: Valley of Ten Thousand Smokes

In 1912, the Novarupta volcano erupted and destroyed 40 square miles of Alaska’s backcountry. Today the valley resembles the desert Southwest, with red mineral deposits covering sections of exposed rock. From the Three Forks Visitor Center, circumvent the valley floor, ascending nearby Broken, Baked, Cerberus, and Falling Mountains. You’ll trek more than 50 miles off-trail and spend over a week in the backcountry. Advanced navigation skills are a must.

Kenai Fjords

Alaska

The Expert: Kyle McDowell, Kenai Backcountry Adventures guide

The Hike: Harding Icefield Trail

A tough but rewarding 8.2-mile round trip hike that gains about 1,000 feet per mile and starts on the valley floor through cottonwoods and alder trees, and offers views of the Exit Glacier even a short distance in. Continue to climb above treeline for views of the Harding Icefield.

Kings Canyon

California

The Expert: Benjamin Cumbie, Sequoia Parks Conservancy, philanthropy and membership manager

The Hike: Redwood Mountain Grove

Tour the largest intact grove of giant sequoias in the world on this 9.9-mile loop, which combines the Hart Tree and Sugar Bowl Trails.

Kobuk Valley

Alaska

The Expert: Nick Allen, Alaska Alpine Adventures guide

The Hike: Great Kobuk Sand Dunes

This remote part of the Arctic Circle has no maintained trails, so you’ll be route-finding in the Alaskan bush. Boreal forest gives way to tundra along the Kobuk River, where you’ll find 25 square miles of sand dunes. Getting there requires a bush plane.

Lake Clark

Alaska

The Expert: Dan Oberlatz, Alaska Alpine Adventures owner and guide

The Hike: Telaquana Route

This ten-day, roughly 40-mile trek from Telaquana Lake to Upper Twin Lake is only for those willing to bushwhack.

Lassen Volcanic

California

The Expert: Sabrina Jurisich, Redding, California hiker

Mammoth Cave

Kentucky

The Expert: Michael Bunch, manager of Nat’s Outdoor Sports in Bowling Green, Kentucky

More than 400 miles of Mammoth Cave have been explored, and the labyrinth boasts the title of world’s longest cave system.

Wind Cave

South Dakota

The Expert: Tom Farrell, Wind Cave National Park chief of interpretation
