National Parks Guide: Best Trails in Every Major Park

The United States has 63 designated national parks, and the wider National Park System of more than 400 sites recorded over 323 million recreation visits in 2025. This guide picks a signature day hike in each of 12 major parks: hikes that capture the defining landscape of each park without requiring mountaineering skills or an overnight trip.

Every trail listed is a day hike for reasonably fit adults, though several involve exposure, scrambling, or desert heat, so read each description before you choose. Distances and elevation figures come from the managing park’s website wherever it publishes them, and permit rules are stated as of October 2026. Reservation systems change from year to year, so confirm on the official park page before you travel.

The West: Rockies and Desert Southwest

Rocky Mountain National Park, Colorado

Sky Pond via Glacier Gorge Trailhead — roughly 8.5 to 10 miles round trip, about 1,700 ft elevation gain, strenuous A classic Rocky Mountain day. The trail passes Alberta Falls, climbs through Loch Vale past The Loch, and ends at Sky Pond, an alpine lake at the head of Loch Vale. The park’s own pages list the one-way distance as 4.2 miles in one place and 4.9 miles in another, with 1,710 to 1,726 feet of gain. Below Sky Pond the route scrambles up wet rock beside Timberline Falls; hands help, but it is not technical climbing. Glacier Gorge Trailhead lies in the Bear Lake Road corridor, which in 2026 required a Timed Entry+ Bear Lake Road reservation from 5 a.m. to 6 p.m. between May 22 and October 18. The parking lot fills early, so the NPS suggests using the Park & Ride lot and the free Bear Lake shuttle when it is running.

Zion National Park, Utah

Angels Landing — 5.4 miles round trip, 1,488 ft elevation gain, strenuous The chain-assisted ridge walk to the summit is Zion’s most famous trail. The NPS describes a route only a few feet wide in places, with sheer drop-offs of as much as 1,000 feet on each side, so it is not suitable for anyone uncomfortable with heights. A permit from Recreation.gov is required to continue past Scout Lookout onto the chains section; as of October 2026 permits are issued through a seasonal lottery that opens months ahead and a day-before lottery. You do not need a permit to hike the West Rim Trail and Walter’s Wiggles to Scout Lookout, which makes a strong hike in its own right. Note that Observation Point can no longer be reached from Zion Canyon because of rockfall closures on the East Rim Trail; it can only be reached by hiking in from the east. For more Zion details, see our Zion trail guide.

Grand Canyon National Park, Arizona

South Kaibab Trail to Skeleton Point — 6 miles round trip, 2,040 ft elevation change, strenuous The South Kaibab follows a ridgeline with open views in every direction, and the NPS says it offers the best views for a relatively short hike. Remember that the climb comes on the way out. The trail is steep, with little shade and no water, and the trailhead is reached by shuttle bus. The NPS asks hikers to check with a ranger before attempting Skeleton Point as a day hike, does not recommend going below it on a day hike, and urges caution from May through September, when inner-canyon temperatures can exceed 110°F. Carry all the water you need and salty food, and turn around at Skeleton Point. Our full Grand Canyon guide covers seasonal recommendations.

Yellowstone National Park, Wyoming

Grand Prismatic Overlook Trail — 1.2 miles round trip, 105 ft elevation gain, easy Grand Prismatic Spring, the largest hot spring in the park, is best appreciated from above. From the Fairy Falls Trailhead, this short trail climbs gently to a viewpoint over the spring and Midway Geyser Basin. For a longer outing, continue on the Fairy Falls Trail, which the NPS describes as a relatively flat, easy 4.5-mile round trip to a waterfall that drops 200 feet. In thermal areas, stay on trails and boardwalks: the ground can be thin crust over scalding water. For backcountry options, see our Yellowstone backcountry guide.

Glacier National Park, Montana

Grinnell Glacier Trail — about 10 miles round trip, roughly 2,600 ft of climbing on the way in, strenuous Alpine meadows, waterfalls, turquoise glacial lakes, and the shrinking Grinnell Glacier itself make this one of the park’s most rewarding hikes. The NPS puts the Grinnell Glacier Viewpoint about 5 miles one way from the Grinnell Glacier Trailhead in the Many Glacier valley; a concessioner boat ride across Swiftcurrent Lake and Lake Josephine drops you 1.3 miles closer. Many Glacier is reached by road from Babb on the park’s east side, not by Going-to-the-Sun Road. The upper trail can stay closed by lingering snow into summer, so check the park’s trail status before you go. This is grizzly country: carry bear spray and make noise on blind corners. See our Glacier trail guide for seasonal access.

Arches National Park, Utah

Delicate Arch Trail — 3 miles round trip, 480 ft elevation gain, moderate The hike to Utah’s best-known arch climbs steadily over open slickrock, passing the Wolfe Ranch cabin and a panel of Ute petroglyphs. The opening beneath Delicate Arch is 46 feet high and 32 feet wide, making it the largest free-standing arch in the park. Shade is scarce, so carry more water than the short distance suggests. Sunset light is the classic choice, but the NPS notes that sunset is also a particularly busy time, sometimes with hundreds of people at the arch.

The Pacific States

Yosemite National Park, California

Mist Trail to Vernal and Nevada Falls — 5.4 miles round trip, 2,000 ft elevation gain, strenuous Spring and early summer deliver the full experience: a granite stairway of more than 600 steps beside the 317-foot Vernal Fall, then steep switchbacks to the top of 594-foot Nevada Fall. Expect slippery footing and heavy spray when the falls are running high, and bring a rain layer. The NPS warns that swimming in Emerald Pool and the Silver Apron above Vernal Fall is illegal and dangerous because of the current. Part of the Mist Trail closes in winter because of ice and rockfall. See our Yosemite guide for more trails.

Mount Rainier National Park, Washington

Skyline Trail Loop — 5.5 miles, 1,700 ft elevation gain, strenuous Starting from Paradise, this loop climbs through subalpine wildflower meadows (typically at their best in midsummer) with Mount Rainier and the Nisqually Glacier close at hand. On a clear day the view from Panorama Point reaches as far south as Oregon’s Mount Hood. The NPS recommends taking the High Skyline Trail past Panorama Point to avoid a steep, icy slope that does not melt out. Our Mount Rainier guide covers the full trail network.

Olympic National Park, Washington

Hoh Rain Forest Hall of Mosses Trail — 0.8-mile loop, minimal elevation, easy The shortest hike on this list delivers one of the most otherworldly landscapes: old-growth temperate rain forest with a grove of bigleaf maples draped in club moss, and ferns carpeting the forest floor. Combine it with the 1.2-mile Spruce Nature Trail, which loops through old and new growth along Taft Creek and the Hoh River. No hiking permit is needed for either trail.

The East and Southeast

Great Smoky Mountains National Park, Tennessee/North Carolina

Alum Cave Trail to Mount Le Conte — 10 miles round trip, strenuous Great Smoky Mountains was the most visited national park in 2025, with about 11.5 million visits, yet its longer trails still reward the effort. The Alum Cave Trail is the shortest of the five routes to Mount Le Conte, passing Arch Rock and the overhanging Alum Cave Bluffs on a long, steady climb to LeConte Lodge, a hike-in lodge near the summit. Turning around at Alum Cave Bluffs (4.6 miles round trip) gives you the highlight with far less effort. The NPS warns of extreme crowding and limited parking at the trailhead on Newfound Gap Road, and a parking tag is required to park in the park; most trailheads have no tag machines, so buy one in advance.

Shenandoah National Park, Virginia

Old Rag Circuit — 9.4 miles, 2,348 ft elevation gain, very strenuous A granite rock scramble near the summit makes Old Rag one of the most demanding day hikes in the East. The scramble requires using your hands and squeezing between boulders; it is not technical rock climbing, but it is physically demanding and not suited to young children or anyone uneasy with exposure. From March 1 to November 30, every Old Rag hiker needs a day-use ticket from Recreation.gov in addition to a park entrance pass. In 2026 the main trailhead lot was closed for construction from May 4 into November, with access from the overflow lots, so check the park’s Old Rag page for the current parking situation.

Acadia National Park, Maine

Precipice Loop — 3.2-mile loop, more than 1,000 ft of climbing, strenuous Iron rungs, ladders, and exposed ledges make the Precipice Trail Acadia’s most thrilling climb: the NPS describes it as rising over 1,000 feet in 0.9 mile to the summit of Champlain Mountain, a rugged, non-technical climb up open cliff faces. It is not recommended for small children, people with a fear of heights, or anyone in wet weather, and the NPS advises against descending the Precipice; return via the Champlain North Ridge Trail and the Orange and Black Path instead. The trail closes each spring while peregrine falcons nest on the cliff (in 2026 the closure began March 1 and lasts until park managers judge it safe to reopen), so have a backup plan. Our Acadia guide covers gentler alternatives.

Best Times to Visit

Spring and fall bring moderate temperatures, smaller crowds, and seasonal displays (wildflowers in spring, foliage in fall) at many parks. Summer is the main season for high-elevation trails such as Sky Pond, Grinnell Glacier, and the Skyline Trail, which can hold snow and ice into early summer and again from autumn, but it is also peak crowd season. Desert and canyon trails are best in the cooler months. Winter opens a different experience entirely — see our winter hiking guide.

Crowds

Visitation is concentrated in a handful of parks and in summer and holiday periods. Starting early is the single most effective way to find parking and quieter trails, and in summer mountain terrain it also gets you off exposed ground before afternoon thunderstorms. For strategies to avoid the worst crowds, see our guide to crowd-free national park trails.
